# The `use` declaration

The `use` declaration can be used to bind a full path to a new name, for easier access.

    // Bind the `deeply::nested::function` path to `other_function`.
    use deeply::nested::function as other_function;

    fn function() {
        println!("called `function()`");
    }

    mod deeply {
        pub mod nested {
            pub fn function() {
                println!("called `deeply::nested::function()`");
            }
        }
    }

    fn main() {
        // Easier access to `deeply::nested::function`
        other_function();

        println!("Entering block");
        {
            // This is equivalent to `use deeply::nested::function as function`.
            // This `function()` will shadow the outer one.
            use deeply::nested::function;
            function();

            // `use` bindings have a local scope. In this case, the
            // shadowing of `function()` is only in this block.
            println!("Leaving block");
        }

        function();
    }
