Fast and efficient network protocols in Rust
summary
Elfo implements a custom Rust protocol with a control TCP connection plus separate data streams, an initial feature-negotiating handshake, and an envelope format that carries protocol and message names. It uses LZ4 compression with a bytes-threshold strategy, TCP-style flow control with windows (example: sender 200 msgs/s, receiver 50 msgs/s, window 100), decoding that can skip unknown messages and runtime registration via linkme virtual tables, and exposes metrics for debugging.
