Introduction

agnostic-lite is an agnostic abstraction layer for any async runtime.

In order to make it trivial for others to build implementations of any async runtime, this crate provides an abstraction layer 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
