easy_reader: “Move forward, backward or randomly through the lines of huge files. Easily and fastly.”
slotmap: “A Rust library providing two containers with persistent unique keys to access stored values”. Good for game entities or graph nodes.
froggy: “Froggy is a prototype for Component Graph System”. Also good for game entities.
generational-arena: “A safe arena allocator that allows deletion without suffering from the ABA problem by using generational indices.” Again this is good for game entities or graph nodes.
Crate of the week suggestion: https://crates.io/crates/cargo-lichking . Attempts to summarize licenses of crates you depend on.
cgroups: “Native Rust library for managing control groups under Linux”.
I’m nominating this because it unlocks the ability to start writing lightweight Docker-like libraries in Rust for Linux!
