Building a Sub-Millisecond Async Serial Port Library in Rust
Most serial port libraries in Rust are synchronous and blocking — fine for scripts, but not for a real-time system where you need to read and react to serial data with sub-millisecond latency. This post walks through how cycbox-serialport wraps a patched fork of serialport-rs to expose a proper tokio::io::AsyncRead / AsyncWrite interface, with platform-native async I/O on both POSIX and Windows. ...
