history

Project history and usage

cargo-msrv helps find, verify, list, show, and set a Rust crate's minimum supported Rust version. Its README defines MSRV as the earliest Rust version supported by a project and documents rustup-backed compatibility checks.

Project history

The crate first appeared on crates.io in October 2019 as version 0.0.0. The official README includes a short history saying cargo-msrv was born from the desire to find the MSRV for a Rust package, and later added tools such as cargo msrv verify.

Adoption history

The tool tracks Rust packaging practice around package.rust-version, added to Cargo for Rust 1.56, while retaining package.metadata.msrv for older MSRVs. It is packaged by Homebrew, Nix, and Arch according to the input facts, and crates.io reported 486,985 downloads when checked on 2026-06-30.

How it is used

Users run cargo msrv find to search for a compatible Rust version, cargo msrv verify to test the declared MSRV, and cargo msrv list or show to inspect author-specified MSRV values in Cargo manifests and dependencies.

Why package nerds care

It matters for package maintainers because MSRV is part of a Rust crate's compatibility contract. cargo-msrv turns that contract into a runnable check for local development and CI.

Timeline

  • 2019: First crates.io release 0.0.0.
  • 2021: Rust 1.56 made package.rust-version available in Cargo manifests, which cargo-msrv's docs recommend for declared MSRV.
  • 2026: Crates.io latest version 0.19.3 and Homebrew stable version 0.19.3.
