Edit `Cargo.toml`

cargo edit provides commands for modifying a Cargo.toml file. It allows you to add, remove, and upgrade dependencies by modifying your Cargo.toml file from the command line.

Currently available subcommands:

cargo upgrade
cargo set-version

Find unused dependencies

`cargo udeps`

udeps ⮳ find unused dependencies in Cargo.toml.

While compilation of this tool also works on Rust stable, it needs Rust nightly to actually run.

`cargo machete`

cargo-machete⮳ is a Cargo tool that detects unused dependencies in Rust projects, in a fast (yet imprecise) way.

Install and run with:

cargo install cargo-machete
cargo machete

Detect dependencies that are out of date

Cargo subcommand for displaying when dependencies are out of date.

If you are using VS Code, also look into the Dependi VS Code plugin.

Lint your crate API changes for semver violations

cargo-semver-checks scans your Rust crate for semver violations.

# If you already use `cargo-binstall` for faster tool installations:
$ cargo binstall cargo-semver-checks

# Otherwise:
$ cargo install cargo-semver-checks --locked

# Lint a new release for SemVer breakage before `cargo publish`:
$ cargo semver-checks
