Rust Coreutils 0.8 is described as bringing "significant" performance gains across core utilities, expanded WebAssembly "WASI" support with a new online playground, and hardening against edge-case panics.
With the expanded WebAssembly support is also a new online playground here for trying out Rust Coreutils within your web browser.
Rust Coreutils 0.8 is passing around 94.74% of all the GNU test suite cases, up 0.15% from the prior release. Rust Coreutils has also removed more unsafe code from different core utilities.
Some of the performance work is leading to the dd command being around 45% faster, faster start-up across utilities, the sort command will now sort paths faster, a 3% gain for numfmt, and various other optimizations.
