Cargo subcommands

Cargo subcommands are specific tools within the Rust package manager used to manage and develop Rust projects. They include commands like `cargo build` (compiling code), `cargo run` (building and executing), `cargo test` (running tests), and `cargo publish` (sharing code on crates.io). These subcommands streamline common development tasks, helping programmers compile, test, package, and distribute their Rust software efficiently. Each subcommand addresses a particular aspect of the project lifecycle, providing a consistent and integrated way to manage Rust codebases effectively.
