Rust-Based CLI Tools

Modern terminals mix classic Unix tools with Rust replacements: faster search, better defaults, and ergonomics that compound daily.

Recipe

# Common installs (macOS brew example)
brew install ripgrep fd bat eza starship
 
# Rust ecosystem via cargo
cargo install cargo-watch cargo-nextest-cli sqlx-cli --locked
cargo install cargo-binstall  # faster prebuilt installs

When to reach for this:

• Onboarding checklist for every Rust developer
• Speeding up search and file navigation
• Local dev loop (cargo watch) matching CI

Working Example

# Dev loop
cargo watch -x 'test -p billing-api'
cargo nextest run --workspace
 
# DB migrations
sqlx migrate run
sqlx prepare --check
 
# Pretty file view with syntax
bat src/main.rs
eza -la --git-ignore

What this demonstrates:

• cargo-watch reruns tests on save
• nextest parallel test runner
• sqlx-cli matches runtime sqlx version

Deep Dive

Recommended Toolbox

cargo-* tools

cargo-audit, cargo-deny, cargo-outdated, cargo-expand, leptosfmt (if Leptos) - add per project needs.

Gotchas

• cargo install without --locked - surprise dependency breaks. Fix: --locked on install.
• PATH not updated - ~/.cargo/bin missing. Fix: rustup shell snippet in profile.
• Duplicate tools - brew and cargo both install rg. Fix: pick one package source.
• Version skew sqlx-cli - migrate format mismatch. Fix: pin CLI version in onboarding doc.
• Heavy cargo install in CI - slow. Fix: use prebuilt binaries or cache ~/.cargo/bin.
