Cargo run
cargo run is a Cargo subcommand that builds and executes a Rust package’s binary target.
Learn Rust in a Month of Lunches
cargo run is a Cargo subcommand that builds and runs a Rust binary target while resolving its dependencies.
- How it is used
- Builds and runs a Rust project while bringing in the external crates its dependencies need.
- How deep it goes
- Walks through dependency-compilation output and a faster incremental rerun without detailing Cargo internals.
- Examples
- Shows a random-letter program using rand and compile logs from its initial and subsequent runs.
- What you can do after
- Operate/configure it to run a Cargo project with a declared external dependency and recognize when dependencies are recompiled.

Rust in Action: Systems programming concepts and techniques
cargo run is a Cargo subcommand that builds a Rust project and executes its resulting binary.
- How it is used
- Runs a Rust project while handling the build needed to produce its executable.
- How deep it goes
- Explains build output, generated files, and common flags, then exposes the compiler invocation with verbose output.
- Examples
- Uses a new Hello World project, a CSV-processing program, and a single-file project migrated to Cargo.
- What you can do after
- Operate/configure it to run a project in debug or release mode and adjust the amount of Cargo output.
