cargo-afl for fuzzing
cargo-asm and cargo-expand to investigate what the compiler generates from your code (cargo-expand shows the expanded output from macros)
cargo-audit for checking whether any of your dependencies are of a version that has a security advisory out against them.
cargo-bloat for identifying what's contributing to your binary's size (eg. modules with generic functions or macros not designed with size-efficiency in mind)
cargo-cache, cargo-sweep, and cargo-prune for keeping disk consumption by build artifacts and other regeneratable files under control.
cargo-deadlinks Check cargo doc output for broken old-style/manual intra-doc links.
cargo-edit for cargo add
cargo-geiger for identifying dependencies with unsafe code so you can either audit them or find alternatives if you don't feel skilled enough to do your own auditing.
cargo-modules for rendering a tree or Graphviz graph of the modules within a crate
cargo-outdated for listing packages that have newer versions than what your Cargo.toml and Cargo.lock are pinning.
cargo-tree to investigate dependencies (I like to use -d to list crates where more than one version is getting pulled in and what's pulling each version in.)
cargo-update to provide a cargo install-update to check for and install new versions of cargo install'd commands.
cargo-watch to re-run a command every time the source changes. (eg. cargo test)
flamegraph as an easy way to generate flamegraphs for visualizing performance profiles of Rust programs.
cargo-about, cargo-deny, cargo-license, or cargo-lichking for license compliance management
cargo-audit and cargo-sweep
cargo-spellcheck
