Different reference kinds in Rust. | ||
|
||
Provides 2 kinds of reference: immutable and mutable. All of them represented in one enum `RefKind`, | ||
which allows you to store immutable and mutable references together. | ||
|
||
In addition, this crate contains `RefKindMap` which is a `HashMap` of reference kinds. | ||
This structure can easily be created from `HashMap` iterator (immutable or mutable one): | ||
|
||
```rust | ||
use std::collections::HashMap; | ||
use ref_kind::RefKindMap; | ||
|
||
let mut map = HashMap::new(); | ||
map.insert("Hello World", 0); | ||
map.insert("The Answer to the Ultimate Question of Life, the Universe, and Everything", 42); | ||
|
||
let mut refs = map.iter_mut().map(|(&k, v)| (k, v)).collect::<RefKindMap<_, _>>(); | ||
``` | ||
|
||
Then it can be used to retrieve multiple mutable references from the `HashMap`: | ||
|
||
```rust | ||
let hello = refs.move_mut("Hello World").unwrap(); | ||
let answer = refs.move_mut("The Answer to the Ultimate Question of Life, the Universe, and Everything").unwrap(); | ||
|
||
assert_eq!(*hello, 0); | ||
assert_eq!(*answer, 42); | ||
``` | ||
|
||
No `unsafe` code is needed! | ||
