A tool for minifying Rust code.

rustminify-cli (Binary)

❯ cargo install rustminify-cli

❯ rustminify --remove-docs <<EOF
//! crate-level doc

fn main() {
    println!("{}", module::f());
}

mod module {
    //! module-level doc

    /// doc for an item
    pub(crate) fn f() -> i32 {
        1 + 1
    }
}
EOF
fn main(){println!("{}",module::f());}mod module{pub(crate)fn f()->i32{1+1}}
