Crate of the Week

The week's Crate of the Week is roaring, the Rust version of Prof. D. Lemire's compressed bitmap data structure. I can personally attest that both the Rust and Java versions compare very favorably in both speed and size to other bit sets and are easy to use.

Thanks to polyfractal for the suggestion.
