Rust - Crates - Paths

To use a module tree, you'll need the path of the module. The path can be:

• Absolute path: Starts at the crate root
• Relative path: Starts from the current module. Uses self, super, or an identifier in the current module.

Which path method used in a module depends on how the module will be used. Absolute paths are generally recommended.

:: separate each identifier in a path (like C++ namespaces).
