Rust Library for the [Riot Games API](https://developer.riotgames.com/).

Rivens's goals are _speed_, _reliability_, and _maintainability_. Riven handles rate limits and large requests with ease.
Data structs and endpoints are automatically generated from the
[Riot API Reference](https://developer.riotgames.com/api-methods/) ([Swagger](http://www.mingweisamuel.com/riotapi-schema/tool/)).

Riven currently uses nightly Rust.

## Features

* Fast, asynchronous, thread-safe.
* Automatically retries failed requests.
* TFT API Support.

## Usage

```rust
use riven::RiotApi;
use riven::consts::Region;

// Riven Enter tokio async runtime.
let rt = tokio::runtime::Runtime::new().unwrap();
rt.block_on(async {
    // Create RiotApi instance from key.
    let api_key = "RGAPI-01234567-89ab-cdef-0123-456789abcdef";
    # let api_key = std::env::var("RGAPI_KEY").ok().or_else(|| std::fs::read_to_string("apikey.txt").ok()).unwrap();
    let riot_api = RiotApi::with_key(api_key);

    // Get summoner data.
    let summoner = riot_api.summoner_v4()
        .get_by_summoner_name(Region::NA, "잘못").await
        .expect("Get summoner failed.")
        .expect("Summoner not found.");

    // Print summoner name.
    println!("{} Champion Masteries:", summoner.name);

    // Get champion mastery data.
    let masteries = riot_api.champion_mastery_v4()
        .get_all_champion_masteries(Region::NA, &summoner.id).await
        .expect("Get champion masteries failed.")
        .unwrap();

    // Print champioon masteries.
    for (i, mastery) in masteries[..10].iter().enumerate() {
        println!("{: >2}) {: <9}    {: >7} ({})", i + 1,
            mastery.champion_id.to_string(),
            mastery.champion_points, mastery.champion_level);
    }
});
```
Output:
```text
