Nested imports with use
A new way to write use
statements has been added to Rust: nested import
groups. If you’ve ever written a set of imports like this:
#![allow(unused)] fn main() { use std::fs::File; use std::io::Read; use std::path::{Path, PathBuf}; }
You can now write this:
#![allow(unused)] fn main() { mod foo { // on one line use std::{fs::File, io::Read, path::{Path, PathBuf}}; } mod bar { // with some more breathing room use std::{ fs::File, io::Read, path::{ Path, PathBuf } }; } }
This can reduce some repetition, and make things a bit more clear.
