What is this?

This crate exports four things:

• A compatibility/abstraction layer for writing async-executor agnostic code. We support two async executors: async-std and tokio. Each may be toggled with a configuration flag.
• A compatibility/abstraction layer for writing async channel agnostic code. We support three async channel implementations: async-std, tokio and flume. Each may be toggled with a configuration flag.
• A library exporting a bunch of useful async primitives.
• A tracing configuration layer optionally supporting console and opentelemetry integration.

Example usage

By default the async-std executor and channels are used.

To use tokio:

RUSTFLAGS='--cfg async_executor_impl="tokio" --cfg async_channel_impl="tokio"' cargo build

async_executor_impl may be either tokio or async-std. async_channel_impl may be either tokio, async-std, or flume.

Note that using tokio channels requires tokio to be the runtime.
