Rust by Example

Using a Library

To link a crate to this new library you may use rustc's --extern flag. All of its items will then be imported under a module named the same as the library. This module generally behaves the same way as any other module.

// extern crate rary; // May be required for Rust 2015 edition or earlier

fn main() {

rary::public_function();

// Error! `private_function` is private

//rary::private_function();

rary::indirect_access();

}

# Where library.rlib is the path to the compiled library, assumed that it's

# in the same directory here:

$ rustc executable.rs --extern rary=library.rlib --edition=2018 && ./executable

called rary's `public_function()`

called rary's `indirect_access()`, that

> called rary's `private_function()`
