Async
Async 是一个 Swift 库，为 Grand Central Dispatch 提供包装器，以简化异步任务和队列的管理。它作为一个任务调度器，用于代码块的执行、计时和编排。
该项目包含一个任务链式处理器，用于在不同线程间序列化操作而无需嵌套回调结构，以及一个将迭代分布在多个线程上的并发循环包装器。它还具有基于令牌的取消系统，用于在挂起操作运行前从执行队列中跟踪并移除它们。
该库通过协调异步组和同步多个任务以在集体完成后触发操作，涵盖了并发管理功能。
Features
- GCD-Based Scheduling - Wraps Grand Central Dispatch queues to execute and time asynchronous code blocks on specific system threads.
- Token-Based Cancellations - Tracks pending operations with unique identifiers to remove them from the execution queue before they run.
- Token-Based Operation Cancellations - Assigns unique identifiers to pending blocks to locate and remove them from the execution queue before they run.
- Parallel Loop Transformers - Transforms standard sequential loops into parallel versions for concurrent execution across multiple threads.
- Parallel Iterators - Runs multiple blocks of code simultaneously by wrapping concurrent iteration functions to reduce total processing time.
- Asynchronous Task Groups - Coordinates multiple asynchronous tasks to track total progress and wait for the entire set to finish.
- Concurrent Loop Distributions - Distributes loop operations across multiple threads using dispatch groups to accelerate processing of large datasets.
- Concurrent Loop Wrappers - Distributes loop iterations across multiple threads using dispatch groups to accelerate data processing.
- Dispatch Group Synchronizations - Tracks multiple concurrent operations and triggers a final completion block once all tasks in the group finish.
- Task Group Synchronizations - Uses dispatch groups to monitor multiple concurrent tasks and trigger a final action upon their collective completion.
- GCD Wrappers - Offers a streamlined Swift interface to simplify the management of asynchronous tasks and queues using Grand Central Dispatch.
- Asynchronous Callback Chains - Provides a flat syntax for sequencing operations across different threads to eliminate deeply nested callback structures.
- Asynchronous Task Cancellation - Stops queued blocks of code from executing to prevent unnecessary processing and save system resources.
- Asynchronous Task Chainers - Sequences operations across different threads to eliminate deeply nested callback structures and pyramid code.
- Pending Task Cancellations - Stops queued execution blocks to prevent unnecessary processing before they are dispatched to the system.
- Concurrency and Scheduling - Syntactic sugar for Grand Central Dispatch.
- Concurrency Tools - Syntactic sugar for GCD asynchronous dispatches.
- Development Utilities - Syntactic sugar for asynchronous GCD dispatching.
- Language Extensions - Syntactic sugar for asynchronous dispatch.
