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.
* TFT API Support.
## Usage
```rust
use riven::RiotApi;
use riven::consts::PlatformRoute;
// 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(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.to_string(),
mastery.champion_points, mastery.champion_level);
}
});
```
Output:
```text

1) Riven 1219895 (7)
2) Fiora 229714 (5)
3) Katarina 175985 (5)

#### Nightly vs Stable
2021-06-30 23:34:34 +00:00
2021-07-04 18:07:56 +00:00
Enable the `nightly` feature to use nightly-only functionality. This enables
2021-06-30 23:34:34 +00:00
[nightly optimizations in the `parking_lot` crate](https://github.com/Amanieu/parking_lot#nightly-vs-stable).
2021-07-04 18:07:56 +00:00
```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
Feel free to [make an issue](https://github.com/MingweiSamuel/Riven/issues/new)
if you are have any questions or trouble with Riven.
## 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.
