Library

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

  1. pub fn public_function() {
  2.     println!("called rary's `public_function()`");
  3. }
  5. fn private_function() {
  6.     println!("called rary's `private_function()`");
  7. }
  9. pub fn indirect_access() {
  10.     print!("called rary's `indirect_access()`, that\n> ");
  12.     private_function();
  13. }
  1. $ rustc --crate-type=lib rary.rs
  2. $ ls lib*
  3. library.rlib

Libraries get prefixed with “lib”, and by default they get named after their
crate file, but this default name can be overridden using the crate_name
attribute.
