# RiteLinked -- HashMap-like containers that hold their key-value pairs in a user controllable order

[![Latest Version](https://img.shields.io/crates/v/ritelinked.svg)](https://crates.io/crates/ritelinked)
[![API Documentation](https://docs.rs/ritelinked/badge.svg)](https://docs.rs/ritelinked)

[RiteLinked](https://crates.io/crates/ritelinked) provides more up to date versions of `LinkedHashMap` & `LinkedHashSet` . 
You can easily use it on `std` or `no_std` environment.

Support some practical feature combinations to help you better embed them in existing code: `serde`, `inline-more` etc. 
Especially, it uses `griddle` by default, if you have a lot of data, it can effectively help you reduce the possible tail delay. (Of course, `hashbrown` can also be used) 

## Usage

Add `ritelinked` to `Cargo.toml`:

```toml
ritelinked = "x.y.z"
```

Write some code like this:

``` rust
let mut lru_cache = LinkedHashMap::new();
let key = "key".to_owned();
let _cached_val = lru_cache
    .raw_entry_mut()
    .from_key(&key)
    .or_insert_with(|| (key.clone(), 42));
```
