Rust's Performance Improvements

Rust programming language updates
Rust programming language updates

Rust is making significant changes that aim to streamline documentation builds. Starting May 1, docs.rs will shift to building only the default target unless specified otherwise. This move not only saves resources but also reduces build times for developers.

Additionally, updates to Rust's WebAssembly targets are on the horizon. The removal of the --allow-undefined flag could break existing projects, so developers should prepare accordingly.
