Crate entry_put_ext

Map entry extension for put operations.

The author of this crate is not good at English. Forgive me if the document is hard to read.

This crate extends result type of the entry methods of the maps (HashMap and BTreeMap) by adding an put methods. These put methods are helper method to set a value of an entry and get a reference to it. This makes common code about setting and getting shortened a little.

Examples

use std::collections::HashMap;
use entry_put_ext::prelude::*;

let mut map = HashMap::from([("X", false)]);
let x = *map.entry("X").put(true);
let y = *map.entry("Y").put(true);

assert_eq!(x, map["X"]);
assert_eq!(y, map["Y"]);
