chore: bump sysinfo to 0.39 and raise MSRV to Rust 1.95#258
Merged
Conversation
sysinfo 0.39 raised its minimum supported Rust version to 1.95 (0.38 required 1.88), so adopting it requires moving the project MSRV, the Docker build base, and every Launchpad PPA toolchain reference from 1.93 to 1.95. The ~lablup/+archive/ubuntu/rustc-release dependency PPA now provides rustc-1.95. sysinfo 0.39's only breaking change is that MSRV bump; none of the public APIs this codebase uses changed, so no source edits were needed. clippy and the full test suite pass unchanged on Rust 1.95. Changes: - Cargo.toml: sysinfo 0.38 -> 0.39, rust-version 1.93 -> 1.95 (plus Cargo.lock) - Dockerfile: rust:1.93-slim -> rust:1.95-slim - .github/workflows/launchpad_ppa.yml: vendor_rust 1.93.0 -> 1.95.0 and the "Rust 1.95+" toolchain descriptions - debian/control and debian/control.source: build-deps to rustc-1.95 | rustc (>= 1.95) and cargo-1.95 | cargo (>= 1.95) - debian/rules, rules.source, rules.launchpad, rules.launchpad-simple: toolchain detection prefers rustc-1.95/cargo-1.95 and the version guard requires >= 1.95 - debian/README.packaging: Rust 1.95 requirement, with the Ubuntu 26.04 (Resolute) note updated since its archived 1.93 no longer meets the floor Historical debian/changelog entries are left intact. Closes #257
