Introduction

agnostic-lite is a Sans-I/O abstraction layer for any async runtime.

In order to make it trivial for others to build implementations of any async runtime, this crate provides a sans-I/O implementation.

In addition, this crate is not only no_std, but also alloc-free. This means that it can be used in environments where alloc is not available, such as embedded systems. It also has no unsafe code.

agnostic-lite splits the big Runtime trait in agnostic in multiple small traits:

• AsyncSpawner: trait for spawning tasks
• AsyncLocalSpawner: trait for spawning local tasks
• AsyncSleep: trait for sleep functionality
• AsyncInterval: trait for interval functionality
• AsyncTimeout: trait for timeout functionality

Builtin supports runtimes:

• tokio
• async-std
• smol
• wasm-bindgen-futures
