From 12f4cb4d8179678c2579152a8c72897787c3bd3d Mon Sep 17 00:00:00 2001 From: jedarden Date: Wed, 20 May 2026 18:58:55 -0400 Subject: [PATCH] feat(pdftract-2w02): pin MSRV to 1.78 with CI gate Add MSRV (Minimum Supported Rust Version) pinning to 1.78 for pdftract-core and pdftract-cli. The MSRV gate prevents silent absorption of newer Rust features that would break downstream consumers on older toolchains. Changes: - CI: Add quality-matrix DAG with msrv-check step (rust:1.78-slim) - CI: Add clippy-check, fmt-check, cargo-audit, cargo-deny templates - README: Add MSRV badge (shields.io) - clippy.toml: Enable msrv=1.78 for MSRV-aware lints - CONTRIBUTING.md: Document MSRV bump policy (MINOR version event) The rust-version was already declared in workspace Cargo.toml; this bead adds the CI enforcement and documentation.
