tokio_h2mux/lib.rs
1//! Multiplexing streams over HTTP/2, built upon [h2](https://docs.rs/h2/).
2//!
3//! Unlike streams opened via the standard HTTP CONNECT method, h2mux streams can be written to
4//! with data immediately after being opened by the client, without waiting 1 extra RTT for the
5//! server to respond to the request.
6//!
7//! It supports auto-scaling HTTP/2 window size based on BDP estimation, ported from [hyper](https://docs.rs/hyper/)
8//! with some params tuned.
