This Week in Rust 669 · This Week in Rust

This week's Rust community roundup covers newsletters, blog posts on topics like Rust on Arduino, FFI, LSP implementation, Tokio performance, WebAssembly panics, and generics dispatch. The crate of the week is zenjpeg, a pure Rust JPEG codec. Compiler team updates include garbage-collecting incremental compilation sessions, stabilizing Vec::from_fn and core::mem::DropGuard, and rustfmt/clippy/rust-analyzer bug fixes. Performance triage shows mostly improvements with Polonius borrow checker performance approaching NLL. No RFCs were approved and no items entered final comment period this week. Upcoming Rust meetups and conferences across virtual, European, North American, and Oceania regions are listed alongside a call for job seekers.
