Finds and verifies the minimum supported Rust version (MSRV) for a Rust project automatically.

Desktopfreeglobal

An open-source command-line tool that automatically discovers and verifies a crate's Minimum Supported Rust Version, replacing manual trial-and-error across multiple toolchains. It helps Rust library maintainers and teams enforcing MSRV policies in CI detect when a declared MSRV becomes outdated; distributed under the Apache-2.0 license for self-hosted use.
