Rust Library for the [Riot Games API](https://developer.riotgames.com/).
|
|
|
|
Riven'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/)).
|
|
|
|
## Design
|
|
|
|
* Fast, asynchronous, thread-safe.
|
|
* Automatically retries failed requests.
|
|
* Supports all endpoints, kept up-to-date using [riotapi-schema](https://github.com/MingweiSamuel/riotapi-schema).
|
|
|
|
## Usage
|
|
|
|
```rust
|
|
use riven::RiotApi;
|
|
use riven::consts::PlatformRoute;
|
|
|
|
// Enter tokio async runtime.
|
|
let rt = tokio::runtime::Runtime::new().unwrap();
|
|
rt.block_on(async {
|
|
// Create RiotApi instance from key string.
|
|
let api_key = std::env!("RGAPI_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(PlatformRoute::NA1, "잘 못").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(PlatformRoute::NA1, &summoner.id).await
|
|
.expect("Get champion masteries failed.");
|
|
|
|
// Print champioon masteries.
|
|
for (i, mastery) in masteries.iter().take(10).enumerate() {
|
|
println!("{: >2}) {: <9} {: >7} ({})", i + 1,
|
|
mastery.champion_id.name().unwrap_or("UNKNOWN"),
|
|
mastery.champion_points, mastery.champion_level);
|
|
}
|
|
});
|
|
```
|
|
Output:
|
|
```text
|
|
잘 못 Champion Masteries:
|

### Feature Flags
|
|
|
|
#### Nightly vs Stable
|
|
|
|
Enable the `nightly` feature to use nightly-only functionality. This enables
|
|
[nightly optimizations in the `parking_lot` crate](https://github.com/Amanieu/parking_lot#nightly-vs-stable).
|
|
|
|
```toml
|
|
riven = { version = "...", features = [ "nightly" ] }
|
|
```
|
|
|
|
#### rustls
|
|
|
|
Riven uses [reqwest](https://github.com/seanmonstar/reqwest) for making requests. By default, reqwest uses the native TLS library.
|
|
If you prefer using [rustls](https://github.com/ctz/rustls) you can do so by turning off the Riven default features
|
|
and specifying the `rustls-tls` feature:
|
|
|
|
```toml
|
|
riven = { version = "...", default-features = false, features = [ "rustls-tls" ] }
|
|
```
|
|
|
|
Riven is additionally able to produce [tracing](https://docs.rs/tracing) spans for requests if the `tracing` feature is enabled. This feature is disabled by default.
|
|
|
|
### Docs
|
|
|
|
[On docs.rs](https://docs.rs/riven/).
|
|
|
|
### Error Handling
|
|
|
|
Riven returns either `Result<T>` or `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 in several situations, such
|
|
as getting a summoner (by name) or match (by id) that doesn't exist, or getting
|
|
spectator data for a summoner who is not in-game.
|
|
Specifically, the API returned a 404 HTTP status code in this situation.
|
|
|
|
The error type used by Riven is `riven::RiotApiError`. It provides some basic
|
|
diagnostic information, such as the source Reqwest error, the number of retries
|
|
attempted, and the Reqwest `Response` object.
|
|
|
|
You can configure the number of time Riven retries using
|
|
`RiotApiConfig::set_retries(...)` and the `RiotApi::with_config(config)`
|
|
constructor. By default, Riven retries up to 3 times (4 requests total).
|
|
Some errors, such as 400 client errors, are not retried as they would
|
|
inevitably fail again.
|
|
|
|
### 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 accessor"
|
|
methods may be removed from `RiotApi` if the corresponding endpoint is removed
|
|
from the Riot API. These breaking changes will increment the **MINOR** version,
|
|
not the major version.
|
|
|
|
Parts of Riven that do not depend on Riot API changes do follow semantic
|
|
versioning.
|
|
|
|
### Additional Help

## Development
|
|
|
|
NodeJS is used to generate code for Riven. The
|
|
[`srcgen/`](https://github.com/MingweiSamuel/Riven/tree/master/srcgen)
|
|
folder contains the code and [doT.js](https://olado.github.io/doT/index.html)
|
|
templates. `index.js` lists the JSON files downloaded and used to generate the
|
|
code.
|
|
|
|
To set up the srcgen, you will first need to install NodeJS. Then enter the
|
|
srcgen folder and run `npm ci` (or `npm install`) to install dependencies.
|
|
|
|
To run the srcgen use `node srcgen` from the main folder.
