rustc

all

The Rust compiler. Rust projects usually use `cargo` instead of invoking `rustc` directly.

Options (1)

-C, --codegenboolean

Compile with optimizations (`s` means optimize for binary size; `z` is the same with even more optimizations)

Example: rustc {{[-C|--codegen]}} lto {{[-C|--codegen]}} opt-level={{0|1|2|3|s|z}} {{path/to/main.rs}}

Compile a binary crate

rustc path/to/main.rs

Compile with optimizations (`s` means optimize for binary size; `z` is the same with even more optimizations)

rustc [-C|--codegen] lto [-C|--codegen] opt-level=0|1|2|3|s|z path/to/main.rs

Compile with debugging information

rustc -g path/to/main.rs

Explain an error message

rustc --explain error_code

Compile with architecture-specific optimizations for the current CPU

rustc [-C|--codegen] target-cpu=native path/to/main.rs

Display the target list (Note: You have to add a target using `rustup` first to be able to compile for it)

rustc --print target-list

Compile for a specific target

rustc --target target_triple path/to/main.rs
