crates-index on Crates.io

Library for retrieving and interacting with the crates.io registry git-based index.

The index contains metadata for all Rust libraries and programs published on crates.io: their versions, dependencies, and feature flags.

Example

let index = crates_index::Index::new_cargo_default()?;

for crate_releases in index.crates() {
    let _ = crate_releases.most_recent_version(); // newest version
    let crate_version = crate_releases.highest_version(); // max version by semver
    println!("crate name: {}", crate_version.name());
    println!("crate version: {}", crate_version.version());
}

Migration from 0.18

It should work without any code changes. Only the git2 and toml dependencies were updated.

Migration from 0.16 and 0.17

  • BareIndex and BareIndexRepo have become the Index.
  • Index::new_cargo_default()? is the preferred way of accessing the index. Use with_path() to clone to a different directory.
  • There's no need to call retrieve() or exists(). It's always retrieved and always exists.
  • retrieve_or_update() is just update().
  • highest_version() returns crate metadata rather than just the version number. Call highest_version().version().parse() to get semver::Version.
  • There's no crate_index_paths(), because there are no files any more. Use crate_ to get individual crates.
