serde 1.0.130 (hash: blake2b24:2e6117acae4f6f2d2d698c9fc0b43de60ac26556f44ad96b)

$ cargo search2 serde --message-format toml serde = "1.0.130"

$ cargo search2 serde --message-format json {"crate-name":"serde","version":"1.0.130","hash":"blake2b24:2e6117acae4f6f2d2d698c9fc0b43de60ac26556f44ad96b"}

Get an exact version or semver range

$ cargo search2 serde --req '=1.0.120' serde 1.0.120 (hash: blake2b24:f79131f50c298569f841e47287c3b0a443c29cfda3ffd475)

Use --cache-version/-c to invalidate caches

$ cargo run -- serde --req '=1.0.120' -c1 serde 1.0.120 (hash: blake2b24:168778241e3b0e96f5547fba1eb4b4b84efa8291c3c14b37) $ cargo run -- serde --req '=1.0.120' -c2 serde 1.0.120 (hash: blake2b24:344d8a8d08a16dbce8c4e0d90fd6aad513631ca081185ea8)

Step outputs for GitHub Actions

$ cargo search2 serde --message-format github ::set-output name=crate-name::serde ::set-output name=version::1.0.120 ::set-output name=hash::blake2b24:f79131f50c298569f841e47287c3b0a443c29cfda3ffd475 ```

For an example GitHub Action, see .github/workflows/example.yml.

Why?

People sometimes use cargo search to generate cache keys for tools. This is an easier way to achieve the same goal with a couple more features.

cargo search2 supports: * looking for exact versions and semver ranges * producing results in plain, JSON, and GitHub Actions formats * easy cache invalidation through the --cache-version option

Hash contents

The hashes produced by cargo search2 are derived from: * The name of the crate * The exact version number * The cache version

Notably, the operating system and other parts of the environment are not part of the hash.

Stability guarantees

Within a semver range, the command-line interface is append-only, and hashes stay the same.
