RUSTFMT STABILIZES HEX LITERAL FORMATTING, RUST-ANALYZER CLEANS HOUSE

By RepoJournal · Filed · About Rust

Rustfmt's long-pending `hex_literal_case` stabilization lands as the ecosystem continues its weekly cadence of refinement across core tooling.

Rustfmt shipped the stabilization of `hex_literal_case` [1], closing out a long-standing issue that lets developers enforce consistent hexadecimal literal formatting across codebases. This addresses a real gap in code style enforcement that teams have been working around for years. Meanwhile, rust-analyzer removed documentation for its deprecated `analysis-bench` command [2], which was already stripped from the codebase. This Week in Rust published issue 655 and opened the draft for 656 [3], including updated RFCs, FCP nominations, and MCP tracking [4]. The project goals repository updated leadership on overloading work, with teor now listed as both contact and implementer [5], reflecting active work on FFI overloading support for 2026. Across the stack, crate index updates continue their regular cadence with new versions of euv and related packages [6], [7], [8].
