Features

  • Replaces extern crate my_lib; in main.rs with the contents of lib.rs.
  • Expands mod my_mod; declarations into mod my_mod { ... } blocks.

Example

Input:

// src/lib.rs:
mod internal;
pub use internal::hello_world;

// src/internal.rs:
pub fn hello_world() {
    println!("Hello, world!");
}

// src/main.rs:
extern crate example;
fn main() {
    example::hello_world();
}

Output:

mod internal {
    pub fn hello_world() {
        println!("Hello, world!");
    }
}
pub use internal::hello_world;
fn main() {
    hello_world();
}
