Let's create a library, and then see how to link it to another crate.
// erty.rs
pub fn public_function() {
println!("called erty's `public_function()`");
}
fn private_function() {
println!("called erty's `private_function()`");
}
pub fn indirect_access() {
print!("called erty's `indirect_access()`, that\n> ");
private_function();
}
$ rustc --crate-type=lib erty.rs
$ ls lib*
liberty.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.
