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:

  • 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}}
