ten, `cargo check` is much faster than
`cargo build` because it skips the step of producing an executable. If you’re
continually checking your work while writing the code, using `cargo check` will
speed up the process of letting you know if your project is still compiling! As
such, many Rustaceans run `cargo check` periodically as they write their
program to make sure it compiles. Then they run `cargo build` when they’re
ready to use the executable.
