async-unsync - Single Threaded Async Channels

A Rust library for asynchronous but unsynchronized (single-threaded) communication primitives, primarily channels and semaphores with an API that is designed to be as similar to tokio::sync as possible.

Most async executors use multi-threaded runtimes and consequently, most synchronization primitives are implemented to be thread-safe, thus incurring the associated synchronization overhead. By restricting their use to single-threaded/thread-local tasks only, the synchronization overhead can be entirely avoided, resulting in up to 10x faster channel operations.

Usage

To use this crate, add the following to your Cargo.toml:

toml [dependencies] async-unsync = "0.1.0"
