Paths

Paths are resolved as follows:

1. As a relative path:

   • foo or self::foo refers to foo in the current module,
   • super::foo refers to foo in the parent module.

2. As an absolute path:

   • crate::foo refers to foo in the root of the current crate,
   • bar::foo refers to foo in the bar crate.

A module can bring symbols from another module into scope with use. You will typically see something like this at the top of each module:

use std::collections::HashSet;
use std::mem::transmute;
