Rust by Example

Creating a Library

Let's create a library, and then see how to link it to another crate.

pub fn public_function() {

println!("called rary's `public_function()`");

}

fn private_function() {

println!("called rary's `private_function()`");

}

pub fn indirect_access() {

print!("called rary's `indirect_access()`, that\n> ");

private_function();

}

$ rustc --crate-type=lib rary.rs

$ ls lib*

library.rlib

Libraries get prefixed with "lib", and by default they get named after their crate file, but this default name can be overridden by passing the --crate-name option to rustc or by using the crate_name attribute.
