Coobjc
coobjc 是一个 Objective-C 协程库，提供 await 方法和生成器，以简化 Objective-C 和 Swift 中的异步编程。它实现了非阻塞工作流，消除了嵌套回调和线程阻塞。
该工具包包括一个非阻塞 Foundation 包装器，可将同步的 Foundation 和 UIKit API 转换为可挂起的操作。它提供了一个用于通过 yield 按需生成值的惰性序列生成器，以及一个基于通道的通信工具，用于使用缓冲和非缓冲通道在并发任务之间交换数据。
该库涵盖了异步任务协调和状态管理，利用 Actor 模型防止数据竞争。其功能包括协程调度、取消，以及在不冻结用户界面的情况下执行文件系统和网络操作的能力。
Features
- Asynchronous Programming - Enables non-blocking workflows in Objective-C and Swift through the implementation of coroutines and await methods.
- Asynchronous Message Passings - Provides an actor model where isolated entities exchange data exclusively through asynchronous message passing.
- Custom Data Channels - Implements communication primitives for exchanging data between concurrent tasks using buffered and unbuffered channels.
- Asynchronous Flow Coordination - Provides patterns for managing the synchronization and resolution of concurrent asynchronous operations.
- Coroutine Launchers - Enables initiating the execution of asynchronous coroutine blocks on specific target queues.
- Lazy Sequences - Provides lazy sequence generators that produce values on demand via yield to handle large data sets efficiently.
- Coroutine Libraries - Provides a comprehensive coroutine library for managing cooperative multitasking and lightweight threads in Objective-C and Swift.
- Block-Based Coroutines - Transforms asynchronous code blocks into state machines to enable non-blocking suspension and resumption.
- Native API Wrappers - Wraps synchronous system APIs into non-blocking operations to maintain user interface responsiveness.
- Non-Blocking API Wrappers - Converts synchronous system calls into suspendable operations compatible with a coroutine runtime.
- Actor-Based Concurrency - Uses isolated, message-passing actors to manage state and execution without data races.
- Asynchronous Task Managers - Offers tools for coordinating complex execution flows using await methods and channels to synchronize concurrent tasks.
- Coroutine Task Schedulers - Manages a queue of lightweight coroutines and distributes them across worker pools for efficiency.
- Lock-Free State Management - Utilizes an actor model to manage shared state and prevent data races in Apple ecosystem applications.
- Coroutine Communication Channels - Provides communication channels for exchanging signals and data between concurrent coroutines.
- CSP Communication Channels - Provides synchronization primitives based on communicating sequential processes for data exchange between concurrent tasks.
- Lazy Sequence Processing - Implements a lazy sequence generator to produce values on demand, reducing memory allocation for large data sets.
- Coroutine Result Awaiting - Allows suspending a coroutine until a promise or channel resolves to return a value.
- Sequential Task Execution - Executes a series of asynchronous computations in a strict linear order to prevent nested callbacks.
- Lazy Data Scanning - Defers data processing until requested to ensure the system only handles data when the consumer is ready.
- Asynchronous Sequence Generators - Implements generators that produce sequences of values where each element is fetched via an async operation.
- Coroutine Suspension Controls - Enables suspending tasks and restoring them later from the last known state using custom calling stacks.
- Custom Execution Stacks - Implements custom call-stack management to restore task state after await calls.
- Lazy Evaluation - Implements lazy evaluation to produce data sequences one item at a time and reduce memory overhead.
- Coroutine Termination - Implements a mechanism to cooperatively stop executing coroutines and perform necessary cleanup.
- Non-blocking IO Implementations - Provides non-blocking implementations for file system and networking operations to maintain user interface responsiveness.
- Asynchronous File I/O - Provides non-blocking interfaces for reading and writing files without stalling the execution thread.
