🐰 Toolchains hop through time, version bumps so fine,
From 1.90 to 1.91, workflows realign!
CI checks dance in workflows three,
Ready for the future, updated with glee! ✨

🔇 Additional comments (3)

.github/workflows/cargo.yml (1)

45-45: Rust toolchain version bump is consistent and isolated.

Version 1.90.0 → 1.91.0 is a straightforward update to the current development toolchain. The comment is preserved correctly.

Please confirm that Rust 1.91.0 is available as a stable release and that there are no known breaking changes affecting this project's CI workflow.

.github/workflows/main.yml (1)

25-25: Consistent Rust version bump across three jobs.

All three instances of the current development toolchain (format, lint, typos jobs) are uniformly updated from 1.90.0 to 1.91.0. The MSRV at line 120 (1.77.0) is correctly left unchanged. Comments are preserved.

Verify that Rust 1.91.0 is available and stable, and confirm no breaking changes affect the formatting, linting, or typos-check tooling between versions.

Also applies to: 42-42, 62-62

.github/workflows/nightly.yml (1)

24-24: Uniform Rust version updates across nightly workflow.

All four toolchain references (audit and checks-with-ci-repo jobs using dtolnay/rust-toolchain, and two semver-checks steps using cargo-semver-checks-action) are consistently updated from 1.90.0 to 1.91.0. Different action parameter names (toolchain vs rust-toolchain) are correctly preserved. Comments are maintained.

Verify that Rust 1.91.0 is available and that cargo-semver-checks-action v2 supports this toolchain version without issues.

Also applies to: 57-57, 93-93, 99-99
