Rust Library for the Riot Games API.

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 (Swagger).


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


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 string.
    let api_key = "RGAPI-01234567-89ab-cdef-0123-456789abcdef";
    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("There is no summoner with that name.");

    // 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.");

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

Nightly vs Stable

Enable the nightly feature to use nightly-only functionality. Mainly enables nightly optimizations in the parking_lot crate. Also required for running async integration tests.


On docs.rs.

Error Handling

Riven returns Result<Option<T>> within futures. If the Result is errored, this indicates that the API request failed to complete successfully, which may be due to bad user input, Riot server errors, incorrect API key, etc. If the Option is None, this indicates that the request completed successfully but no data was returned. This happens if a summoner (by name) or match (by id) doesn't exist.
