Can you call a Rust library from Go without Cgo or WebAssembly? Yes, but it’s tricky, has risks, and isn't advised for every situation. Semih Alev 💡 [purego](https://github.com/ebitengine/purego) offers a similar, though more general, approach to this problem. [A Fast Immutable Map in Go (with Tradeoffs)](https://lemire.me/blog/2026/03/29/a-fast-immutable-map-in-go/) — [constmap](https://github.com/lemire/constmap) gets you 3x faster lookups and 6x less memory used per key than `map`, but with several tradeoffs, including only offering `string` to `uint64` mapping, being unable to tell if a key is missing, and increased construction time.
