# cargo rustc
> Compile a Rust package. Similar to `cargo build`, but you can pass extra options to the compiler.
> See `rustc --help` for all available options.
> More information: <https://doc.rust-lang.org/cargo/commands/cargo-rustc.html>.
- Build the package and pass options to `rustc`:
`cargo rustc -- {{rustc_options}}`
- Build artifacts in release mode, with optimizations:
`cargo rustc --release`
- Compile with architecture-specific optimizations for the current CPU:
`cargo rustc --release -- -C target-cpu=native`
- Compile with speed optimizations:
`cargo rustc -- -C opt-level {{1|2|3}}`
- Compile with [s]ize optimizations (`z` also turns off loop vectorization):
`cargo rustc -- -C opt-level {{s|z}}`
- Check if your package uses unsafe code:
`cargo rustc --lib -- -D unsafe-code`
- Build a specific package:
`cargo rustc --package {{package}}`
- Build only the specified binary:
`cargo --bin {{name}}`
