cargo

cargo comes preinstalled with rustup.

Usage

• cargo new → either creates a new folder with a Cargo.toml, a src/main.rs and initializes a git repo (by default).

• cargo init in a preexisting folder.

• cargo new --vcs → to change the version control tool.

• cargo build to compile and create an executable. --debug (which is by default) compiles faster then --release.

• cargo run to compile and immediatly run the resulting executable, without making an executable. Faster then build

• cargo check to check the code without making an executable nor running the program. Serves to check if the program still compiles. It is faster then run and build.

• cargo run/build --offline to use local offline dep instead of online.

• cargo add to add dependencies to the project (and automatically in the Cargo.toml).

External tooling

• cargo-upgrades
• cargo-edit

Both tools, when installed, can help automatically upgrade dependencies to latest compatible version.
