Running in Rust primarily involves using the command `cargo run` in your project's directory. This command compiles your code and executes the resulting binary. Make sure your main function is defined, as it serves as the entry point. For a more efficient workflow, continuously monitor changes by incorporating `cargo watch`, which automatically rebuilds your project whenever files are modified.
