Type-check without producing binaries
Validate code quickly without final artifacts.
bashANYcargocheck
bash
cargo checkNotes
Faster than a full build for many edit-compile cycles.
Rust CLI Build, Run, Test, and Lint
Everyday Cargo workflows for checking, building, running, testing, formatting, linting, and cleaning Rust CLI projects.
Export
Copy the compact sheet, download it, or print it.
Download
`D` dense toggle · `C` copy all
Build and run
Fast iteration commands for local development.
bash
cargo buildNotes
Builds binaries and libraries for selected packages and targets.
bash
cargo build --releaseNotes
Uses the `release` profile for optimized builds.
bash
cargo runNotes
Pass app arguments after `--` when needed.
bash
cargo run -- --helpNotes
Arguments after `--` are forwarded to the compiled binary.
Run a specific binary target
Choose which binary to execute in multi-bin packages.
bashANYcargorunbin
bash
cargo run --bin admin-toolNotes
Useful when the package exposes more than one executable.
bash
cargo run --example demoNotes
Examples can be useful for smoke tests and documentation.
Tests and benches
Test execution, filtering, and output control.
bash
cargo testNotes
The default workflow for unit tests, integration tests, and doctests.
bash
cargo test parse_argsNotes
Great for tight feedback loops while debugging one area.
bash
cargo test -- --nocaptureNotes
The flags after the separator go to the test harness, not Cargo.
bash
cargo test -- --test-threads=1Notes
Helps when tests share global state or external ports.
bash
cargo benchNotes
Benchmark support is available through Cargo benchmark targets.
Formatting, linting, cleaning
Keep code consistent and remove stale artifacts.
bash
cargo fmtNotes
Requires the rustfmt component to be installed.
bash
cargo fmt -- --checkNotes
Common CI guard to enforce formatting.
bash
cargo clippyNotes
Requires the Clippy component to be installed.
bash
cargo clippy -- -D warningsNotes
A stricter CI pattern for keeping lint debt low.
bash
cargo cleanNotes
Useful when debugging stale builds or reclaiming disk space.
Profiles and target selection
Build specific targets or profiles.
bash
cargo build --bin admin-toolNotes
Targets can be selected individually in multi-target packages.
bash
cargo build --example demoNotes
Useful for verifying example code compiles.
bash
cargo test --no-runNotes
Good for CI stages or debugging compilation failures in tests.
Check all package targets
Type-check binaries, tests, examples, and benches.
bashANYcargochecktargets
bash
cargo check --all-targetsNotes
Broad validation helps catch code paths not built by default.
