sansio

Async/await state machine for the sans-io design pattern.

The Idea

This crate is a experiment for Sans I/O in Rust (see sans I/O for network protocols documentation to familiar with the concept). Writing network protocol without performing I/O operations means creating a state machine. Manually creating a state machine could be a tedious process. As Rust async/await concept is an actual state machine with implicit states created during compilation, this library is an experiment with using async/await to provide such state machine automatically. Let's check if this is good solution to the problem.

Dependency

It is no_std crate without allocations on the heap. It depends only on the core, no other crates. Only examples uses std, clap and tokio as dev-dependencies.
