🔇 Additional comments (3)

devicemapper-rs-sys/Cargo.toml (1)

6-6: MSRV update looks correct.

The rust-version is consistently updated to 1.85.0, aligning with the root Cargo.toml and CI workflow changes. The descriptive comment helps maintainability.

.github/workflows/main.yml (1)

64-65: CI matrix correctly updated for MSRV testing.

The lowest supported toolchain is properly updated to 1.85.0 while maintaining the development toolchain at 1.92.0. This ensures the crate is tested against both the minimum and current Rust versions.

Cargo.toml (1)

13-13: MSRV update is consistent across the workspace.

The rust-version bump to 1.85.0 is correctly synchronized across root Cargo.toml, devicemapper-rs-sys/Cargo.toml, and .github/workflows/main.yml. All three locations now consistently declare 1.85.0 as the minimum supported Rust version, which is a valid stable release.
