rustgo: calling Rust from Go with near-zero overhead

This post describes an experiment to call Rust code from Go with near-zero overhead, aimed at replacing assembly code for cryptographic operations. It explains why Rust is chosen over assembly and cgo, details the linking process, and provides a working example that integrates Rust and Go. The post concludes with performance benchmarks showing that rustgo is significantly faster than cgo and almost as fast as a Go function call.
