Riven

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).

Design

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

Usage

use riven::RiotApi;
use riven::consts::Region;

// Enter tokio async runtime.
let mut 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";
    # /* (doc testing) */ let api_key = std::env!("RGAPI_KEY");
    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_id.to_string(),
            mastery.champion_points, mastery.champion_level);
    }
});

Output:

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.

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.

Semantic Versioning

This package follows semantic versioning to an extent. However, the Riot API itself changes often and does not follow semantic versioning, which makes things difficult. Out-of-date versions will slowly partially cease to work due to this.

When the API changes, this may result in breaking changes in the models module, endpoints module, and some of the consts module. "Handle accessors" may be removed from RiotApi if the corresponding endpoint is removed from the Riot API. These changes will increment the MINOR version.

Parts of Riven that do not depend on Riot API changes do follow semantic versioning.
