Async Std
async-std is a Rust asynchronous runtime and non-blocking I/O library. It serves as an asynchronous standard library, providing a set of alternatives to the core Rust library for managing concurrent tasks, networking, and file system access.
The project implements a standard-library-mirrored API, offering asynchronous versions of existing synchronous types to maintain a familiar interface. This approach allows for asynchronous Rust development using an interface that reflects the ergonomics of the language's standard library.
The runtime includes a task executor for scheduling and executing asynchronous operations across multiple threads. Its capability surface covers concurrent task execution, non-blocking input and output operations, and general runtime management.
Features
