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");
