About

async-callback-manager is a crate designed to help you manage an asynchronous callback pattern when developing Rust UI.

This is initially designed as a dependency of the youtui music player, however could have wider applicability.

Basic usage

The AsyncCallbackManager should live with your event loop, and can produce a stream of events corresponding to a component callback or an asynchronous task.

From the AsyncCallbackManager you can create AsyncCallbackSenders that allow you to log asynchronous callbacks and receive their replies as a list of state mutations to be applied.

Examples

A runnable example using ratatui is provided in the examples directory. cargo r --example=ratatui_example.
