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 {{[-r|--release]}}

• Compile with architecture-specific optimizations for the current CPU:

cargo rustc {{[-r|--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 {{[-p|--package]}} {{package}}

• Build only the specified binary:

cargo rustc --bin {{name}}
