cratesinfo

A fast CLI tool to get detailed information about Rust crates from crates.io — like pipinfo for PyPI or npm info for Node, but for the Rust/Cargo ecosystem.

GitHub Actions

Three workflows are included:

Workflow	Trigger	What it does
ci.yml	Push / PR	Format check, Clippy lint, build+test on Linux/Windows/macOS
release.yml	git push --tags (e.g. v0.2.0)	Cross-compiles 5 platform binaries, creates GitHub Release with all assets + SHA256SUMS
publish.yml	GitHub Release published	cargo publish to crates.io

Releasing a new version

# 1. bump version in Cargo.toml
# 2. commit + tag
git add Cargo.toml Cargo.lock
git commit -m "chore: release v0.2.0"
git tag v0.2.0
git push origin main --tags
# → release.yml builds all 5 binaries and creates the GitHub Release automatically

For cargo publish to work, add your crates.io API token as a repository secret named CARGO_REGISTRY_TOKEN in Settings → Secrets and variables → Actions.
