How deeply does Learn Rust in a Month of Lunches cover cargo build?

Explains ahead-of-time and incremental compilation, but defers detailed build configuration.

Cargo build

As explained in Learn Rust in a Month of Lunches

cargo build is a Cargo command that compiles a Rust program into an executable artifact.

cargo build compiles a Rust program ahead of time. Run it after adding an external crate so Cargo can compile the code while you work; later builds reuse unchanged results through incremental compilation. section 18.1.2

A faster follow-up build

After changing a program that uses an external crate, run cargo build. Cargo avoids recompiling unchanged crates, so the next cargo build or cargo run usually finishes much faster. section 18.1.2

   Compiling random_test v0.1.0 (C:\rust\random_test)
    Finished dev [unoptimized + debuginfo] target(s) in 0.55s
     Running `target\debug\random_test.exe`

Use the compilation output to recognize a completed build and see the shorter incremental-build time. section 18.1.2
