+
+_Benchmark suite for cherrypick DI container, get_it, and other DI solutions._
+
+## Overview
+
+benchmark_di is a flexible benchmarking suite to compare DI containers (like cherrypick and get_it) on synthetic, deep, and real-world dependency scenarios – chains, factories, async, named, override, etc.
+
+**Features:**
+- Universal registration layer and modular scenario setup (works with any DI)
+- Built-in support for [cherrypick](https://github.com/) and [get_it](https://pub.dev/packages/get_it)
+- Clean CLI for matrix runs and output formats (Markdown, CSV, JSON, pretty)
+- Reports metrics: timings, memory (RSS, peak), statistical spreads, and more
+- Extendable via your own DIAdapter or benchmark scenarios
+
+---
+
+## Benchmark Scenarios
+
+- **registerSingleton**: Simple singleton registration/resolution
+- **chainSingleton**: Resolution of long singleton chains (A→B→C...)
+- **chainFactory**: Chain resolution via factories (new instances each time)
+- **asyncChain**: Async chain (with async providers)
+- **named**: Named/qualified resolution (e.g. from multiple implementations)
+- **override**: Resolution and override in subScopes/child adapters
+
+---
+
+## Supported DI
+
+- **cherrypick** (default)
+- **get_it**
+- Easy to add your own DI by creating a DIAdapter
+
+Switch DI with the CLI option: `--di`
+
+---
+
+## How to Run
+
+1. **Install dependencies:**
+   ```shell
+   dart pub get
+   ```
+
+2. **Run all benchmarks (default: all scenarios, 2 warmup, 2 repeats):**
+   ```shell
+   dart run bin/main.dart --benchmark=all --format=markdown
+   ```
+
+3. **For get_it:**
+   ```shell
+   dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+   ```
+
+4. **Show all CLI options:**
+   ```shell
+   dart run bin/main.dart --help
+   ```
+
+### CLI Parameters
+
+- `--di` — DI implementation: `cherrypick` (default) or `getit`
+- `--benchmark, -b` — Scenario: `registerSingleton`, `chainSingleton`, `chainFactory`, `asyncChain`, `named`, `override`, `all`
+- `--chainCount, -c` — Number of parallel chains (e.g. `10,100`)
+- `--nestingDepth, -d` — Chain depth (e.g. `5,10`)
+- `--repeat, -r` — Measurement repeats (default: 2)
+- `--warmup, -w` — Warmup runs (default: 1)
+- `--format, -f` — Output: `pretty`, `csv`, `json`, `markdown`
+- `--help, -h` — Usage
+
+### Run Examples
+
+- **All benchmarks for cherrypick:**
+  ```shell
+  dart run bin/main.dart --di=cherrypick --benchmark=all --format=markdown
+  ```
+
+- **For get_it (all scenarios):**
+  ```shell
+  dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+  ```
+
+- **Specify chains/depth matrix:**
+  ```shell
+  dart run bin/main.dart --benchmark=chainSingleton --chainCount=10,100 --nestingDepth=5,10 --repeat=3 --format=csv
+  ```
+
+---
+
+## Universal DI registration: Adapter-centric approach
+
+Starting from vX.Y.Z, all DI registration scenarios and logic are encapsulated in the adapter itself via the `universalRegistration` method.
+
+### How to use (in Dart code):
+
+```dart
+final di = CherrypickDIAdapter(); // or GetItAdapter(), RiverpodAdapter(), etc
+
+di.setupDependencies(
+  di.universalRegistration(
+    scenario: UniversalScenario.chain,
+    chainCount: 10,
+    nestingDepth: 5,
+    bindingMode: UniversalBindingMode.singletonStrategy,
+  ),
+);
+```
+- There is **no more need to use any global function or switch**: each adapter provides its own type-safe implementation.
+
+### How to add a new scenario or DI:
+- Implement `universalRegistration<S extends Enum>(...)` in your adapter
+- Use your own Enum if you want adapter-specific scenarios!
+- Benchmarks and CLI become automatically extensible for custom DI and scenarios.
+
+### CLI usage (runs all universal scenarios for Cherrypick, GetIt, Riverpod):
+
+```
+dart run bin/main.dart --di=cherrypick --benchmark=all
+dart run bin/main.dart --di=getit --benchmark=all
+dart run bin/main.dart --di=riverpod --benchmark=all
+```
+
+See the `benchmark_di/lib/di_adapters/` folder for ready-to-use adapters.
+
+---
+## Advantages
+
+- **Type-safe:** Zero dynamic/object usage in DI flows.
+- **Extensible:** New scenarios are just new Enum values and a method extension.
+- **No global registration logic:** All DI-related logic is where it belongs: in the adapter.
+
+=======
+## How to Add Your Own DI
+
+1. Implement a class extending `DIAdapter` (`lib/di_adapters/your_adapter.dart`)
+2. Implement the `universalRegistration<S extends Enum>(...)` method directly in your adapter for type-safe and scenario-specific registration
+3. Register your adapter in CLI (see `cli/benchmark_cli.dart`)
+4. No global function needed — all logic is within the adapter!

+
+_Бенчмаркинговый набор для cherrypick, get_it и других DI-контейнеров._
+
+## Общее описание
+
+benchmark_di — это современный фреймворк для измерения производительности DI-контейнеров (как cherrypick, так и get_it) на синтетических, сложных и реальных сценариях: цепочки зависимостей, factory, async, именованные биндинги, override и пр.
+
+**Возможности:**
+- Универсальный слой регистрации сценариев (работает с любым DI)
+- Готовая поддержка [cherrypick](https://github.com/) и [get_it](https://pub.dev/packages/get_it)
+- Удобный CLI для запусков по матрице значений параметров и различных форматов вывода (Markdown, CSV, JSON, pretty)
+- Сбор и вывод метрик: время, память (RSS, peak), статистика (среднее, медиана, stddev, min/max)
+- Легко расширять — создавайте свой DIAdapter и новые сценарии
+
+---
+
+## Сценарии бенчмарков
+
+- **registerSingleton**: Регистрация и резолвинг singleton
+- **chainSingleton**: Разрешение длинных singleton-цепочек (A→B→C…)
+- **chainFactory**: То же, но с factory (каждый раз — новый объект)
+- **asyncChain**: Асинхронная цепочка (async factory/provider)
+- **named**: Разрешение по имени (например, из нескольких реализаций)
+- **override**: Переопределение зависимостей в subScope
+
+---
+
+## Поддерживаемые DI-контейнеры
+
+- **cherrypick** (по умолчанию)
+- **get_it**
+- Легко добавить свой DI через DIAdapter
+
+Меняется одной CLI-опцией: `--di`
+
+---
+
+## Как запустить
+
+1. **Установить зависимости:**
+   ```shell
+   dart pub get
+   ```
+
+2. **Запустить все бенчмарки (по умолчанию: все сценарии, 2 прогрева, 2 замера):**
+   ```shell
+   dart run bin/main.dart --benchmark=all --format=markdown
+   ```
+
+3. **Для get_it:**
+   ```shell
+   dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+   ```
+
+4. **Показать все опции CLI:**
+   ```shell
+   dart run bin/main.dart --help
+   ```
+
+### Параметры CLI
+
+- `--di` — Какой DI использовать: `cherrypick` (по умолчанию) или `getit`
+- `--benchmark, -b` — Сценарий: `registerSingleton`, `chainSingleton`, `chainFactory`, `asyncChain`, `named`, `override`, `all`
+- `--chainCount, -c` — Сколько параллельных цепочек (например, `10,100`)
+- `--nestingDepth, -d` — Глубина цепочки (например, `5,10`)
+- `--repeat, -r` — Повторов замера (по умолчанию 2)
+- `--warmup, -w` — Прогревочных запусков (по умолчанию 1)
+- `--format, -f` — Формат отчёта: `pretty`, `csv`, `json`, `markdown`
+- `--help, -h` — Справка
+
+### Примеры запуска
+
+- **Все бенчмарки для cherrypick:**
+  ```shell
+  dart run bin/main.dart --di=cherrypick --benchmark=all --format=markdown
+  ```
+
+- **Для get_it (все сценарии):**
+  ```shell
+  dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+  ```
+
+- **Запуск по матрице параметров:**
+  ```shell
+  dart run bin/main.dart --benchmark=chainSingleton --chainCount=10,100 --nestingDepth=5,10 --repeat=3 --format=csv
+  ```
+
+---
+
+## Универсальная регистрация зависимостей: теперь через adapter
+
+В версии X.Y.Z вся логика сценариев регистрации DI-инфраструктуры локализована в adapter через метод `universalRegistration`.
+
+### Использование в Dart:
+
+```dart
+final di = CherrypickDIAdapter(); // или GetItAdapter(), RiverpodAdapter() и т.д.
+
+di.setupDependencies(
+  di.universalRegistration(
+    scenario: UniversalScenario.chain,
+    chainCount: 10,
+    nestingDepth: 5,
+    bindingMode: UniversalBindingMode.singletonStrategy,
+  ),
+);
+```
+- **Теперь нет необходимости вызывать глобальные функции или switch-case по типу DI!** Каждый adapter сам предоставляет типобезопасную функцию регистрации.
+
+### Как добавить новый сценарий или DI:
+
+- Реализуйте метод `universalRegistration<S extends Enum>(...)` в своём adapter.
+- Можно использовать как UniversalScenario, так и собственные enum-сценарии!
+- Бенчмарки CLI автоматически расширяются под ваш DI и ваши сценарии, если реализован метод-расширение.
+
+### Запуск CLI (все сценарии DI Cherrypick, GetIt, Riverpod):
+
+```
+dart run bin/main.dart --di=cherrypick --benchmark=all
+dart run bin/main.dart --di=getit --benchmark=all
+dart run bin/main.dart --di=riverpod --benchmark=all
+```
+
+Смотрите примеры готовых adapters в `benchmark_di/lib/di_adapters/`.
+
+## Преимущества
+
+- **Type-safe:** Исключено использование dynamic/object в стороне DI.
+- **Масштабируемость:** Новый сценарий — просто enum + метод в adapter.
+- **Вся логика регистрации теперь только в adapter:** Добавление или изменение не затрагивает глобальные функции.

+
+1. **RegisterSingleton** — Registers and resolves a singleton. Baseline DI speed.
+2. **ChainSingleton** — A dependency chain A → B → ... → N (singleton). Deep singleton chain resolution.
+3. **ChainFactory** — All chain elements are factories. Stateless creation chain.
+4. **AsyncChain** — Async chain (async factory). Performance on async graphs.
+5. **Named** — Registers two bindings with names, resolves by name. Named lookup test.
+6. **Override** — Registers a chain/alias in a child scope. Tests scope overrides.

+
+## Analysis
+
+- **get_it** is the absolute leader in all scenarios, especially under deep/nested chains and async.
+- **cherrypick** is highly competitive and much faster than riverpod on any complex graph.
+- **riverpod** is only suitable for small/simple DI graphs due to major slowdowns with depth, async, or override.
+
+### Recommendations
+- Use **get_it** for performance-critical and deeply nested graphs.
+- Use **cherrypick** for scalable/testable apps if a small speed loss is acceptable.
+- Use **riverpod** only if you rely on Flutter integration and your DI chains are simple.

+# Сравнительный отчет DI-бенчмарка: cherrypick vs get_it vs riverpod
+
+## Описание сценариев
+
+1. **RegisterSingleton** — регистрация и получение объекта-синглтона (базовая скорость DI).
+2. **ChainSingleton** — цепочка зависимостей A → B → ... → N (singleton). Глубокий singleton-резолвинг.
+3. **ChainFactory** — все элементы цепочки — фабрики. Stateless построение графа.
+4. **AsyncChain** — асинхронная цепочка (async factory). Тестирует async/await граф.
+5. **Named** — регистрация двух биндингов с именами, разрешение по имени.
+6. **Override** — регистрация биндинга/цепочки в дочернем scope. Проверка override/scoping.

+
+## Краткий анализ и рекомендации
+
+- **get_it** всегда лидер, особенно на глубине/асинхронных графах.
+- **cherrypick** заметно быстрее riverpod на сложных сценариях, опережая его в разы.
+- **riverpod** подходит только для простых/небольших графов — при росте глубины или async/override резко проигрывает по скорости.
+
+### Рекомендации
+- Используйте **get_it** для критичных к скорости приложений/сложных графов зависимостей.
+- Выбирайте **cherrypick** для масштабируемых, тестируемых архитектур, если микросекундная разница не критична.
+- **riverpod** уместен только для реактивного UI или простых графов DI.

+### Fast Dependency Lookup (Performance Improvement)
+
+> **Performance Note:**  
+> **Starting from version 3.0.0**, CherryPick uses a Map-based resolver index for dependency lookup. This means calls to `resolve<T>()` and related methods are now O(1) operations, regardless of the number of modules or bindings in your scope. Previously, the library had to iterate over all modules and bindings to locate the requested dependency, which could impact performance as your project grew.
+>
+> This optimization is internal and does not change any library APIs or usage patterns, but it significantly improves resolution speed in larger applications.

+## Logging
+
+CherryPick supports centralized logging of all dependency injection (DI) events and errors. You can globally enable logs for your application or test environment with:
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  // Set a global logger before any scopes are created
+  CherryPick.setGlobalLogger(PrintLogger()); // or your custom logger
+
+  final scope = CherryPick.openRootScope();
+  // All DI actions and errors will now be logged!
+}
+```
+- All dependency resolution, scope creation, module installation, and circular dependency errors will be sent to your logger (via info/error method).
+- By default, logs are off (SilentLogger is used in production).
+
+If you want fine-grained, test-local, or isolated logging, you can provide a logger directly to each scope:
+
+```dart
+final logger = MockLogger();
+final scope = Scope(null, logger: logger); // works in tests for isolation
+scope.installModules([...]);
+```

+
+## Quick Guide: Circular Dependency Detection
+
+CherryPick can detect circular dependencies in your DI configuration, helping you avoid infinite loops and hard-to-debug errors.
+
+**How to use:**
+
+### 1. Enable Cycle Detection for Development
+
+**Local detection (within one scope):**
+```dart
+final scope = CherryPick.openSafeRootScope(); // Local detection enabled by default
+// or, for an existing scope:
+scope.enableCycleDetection();
+```
+
+**Global detection (across all scopes):**
+```dart
+CherryPick.enableGlobalCrossScopeCycleDetection();
+final rootScope = CherryPick.openGlobalSafeRootScope();
+```
+
+### 2. Error Example
+
+If you declare mutually dependent services:
+```dart
+class A { A(B b); }
+class B { B(A a); }
+
+scope.installModules([
+  Module((bind) {
+    bind<A>().to((s) => A(s.resolve<B>()));
+    bind<B>().to((s) => B(s.resolve<A>()));
+  }),
+]);
+
+scope.resolve<A>(); // Throws CircularDependencyException
+```
+
+### 3. Typical Usage Pattern
+
+- **Always enable detection** in debug and test environments for maximum safety.
+- **Disable detection** in production for performance (after code is tested).
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  runApp(MyApp());
+}
+```
+
+### 4. Handling and Debugging Errors
+
+On detection, `CircularDependencyException` is thrown with a readable dependency chain:
+```dart
+try {
+  scope.resolve<MyService>();
+} on CircularDependencyException catch (e) {
+  print('Dependency chain: ${e.dependencyChain}');
+}
+```

+### Fast Dependency Lookup (Performance Improvement)
+
+> **Performance Note:**  
+> **Starting from version 3.0.0**, CherryPick uses a Map-based resolver index for dependency lookup. This means calls to `resolve<T>()`, `tryResolve<T>()` and similar methods are now O(1) operations, regardless of the number of modules or bindings within your scope. Previously it would iterate over all modules and bindings, which could reduce performance as your project grew. This optimization is internal and does not affect the public API or usage patterns, but significantly improves resolution speed for larger applications.

+
+> **Примечание по производительности:**  
+> Начиная с версии **3.0.0**, CherryPick для поиска зависимости внутри scope использует Map-индекс.

Ранее для поиска приходилось перебирать весь список вручную, что могло замедлять работу крупных приложений. Это внутреннее улучшение не меняет внешнего API или паттернов использования, но заметно ускоряет разрешение зависимостей на больших проектах.
