Example
A hello world program looks like:
fn main() {
println!("Hello World!");
}To compile and run the program, try:
rustc hello.rs ./hello
It is more common to use cargo(1), which wraps rustc(1). It depends on the project following a standard file structure, and on being in the project's root directory.
cargo build --release ./hello # or cargo run
The release flag enables all optimizations. These optimizations are also accessible with rustc(1), but through multiple flags and options.
