rust-toolchain.toml

[toolchain]
# Pin to a specific stable version so CI and local use the EXACT same
# compiler. With `channel = "stable"`, CI runners (dtolnay/rust-
# toolchain@stable) always grab the latest stable while local dev
# machines run whatever version was last installed — a clippy lint
# added in a newer stable then breaks CI without firing locally
# (this happened on 2026-04-27: `unnecessary_sort_by` landed in
# clippy 1.95 while a dev box had 1.92). Pinning makes "passes
# locally" = "passes in CI" for every check that depends on the
# toolchain.
#
# Bump procedure: edit the channel string here, run `rustup update`,
# run `make ci-precheck`, fix any new lints, commit.
