# rosu
rosu is a wrapper for [osu!](https://osu.ppy.sh/home) written in rust.
The wrapper provides access to the [osu!api](https://github.com/ppy/osu-api/wiki)'s
beatmap, user, score, user-best, user-recent, and match endpoints
with a request struct for each endpoint, e.g. [`BestRequest`] for the user-best endpoint.
Simply initialize an [`Osu`] client, formulate a request such as a [`UserRequest`],
and then retrieve the data by calling the request's `queue` method with a reference to the
client as argument.
[`UserRequest`]: backend/requests/struct.UserRequest.html
[`BestRequest`]: backend/requests/struct.BestRequest.html
[`Osu`]: backend/struct.Osu.html
### Examples
```rust
use chrono::{offset::TimeZone, DateTime, Utc};
use rosu::{
backend::{BeatmapRequest, BestRequest, MatchRequest, UserRequest},
models::*,
Osu, OsuError,
};
#[tokio::main]
async fn main() -> Result<(), OsuError> {
// Initialize the client
let osu = Osu::new("osu_api_key".to_owned());
// --- Retrieving top scores ---
// Accumulate all important arguments for the request
let request = BestRequest::with_username("Badewanne3")
.mode(GameMode::MNA)
.limit(4);
// Asynchronously send the request through the osu client
let mut scores: Vec<Score> = request.queue(&osu).await?;
match scores.pop() {
Some(score) => {
// Retrieve user of the score
let user = score.get_user(&osu, GameMode::STD).await?;
// ...
}
None => println!("No top scores found"),
}
// --- Retrieving beatmaps ---
let since_date: DateTime<Utc> = Utc
.datetime_from_str("2018-11-13 23:01:28", "%Y-%m-%d %H:%M:%S")
.unwrap();
let request = BeatmapRequest::new()
.mode(GameMode::MNA)
.limit(3)
.since(since_date)
.mapset_id(945496);
let mut maps: Vec<Beatmap> = request.queue(&osu).await?;
if let Some(map) = maps.pop() {
let leaderboard: Vec<Score> = map.get_global_leaderboard(&osu, 13).await?;
// ...
}
// --- Retrieving user ---
let user = UserRequest::with_username("Badewanne3")
.queue_single(&osu)
.await?;
// ...
// --- Retrieving match ---
let osu_match = MatchRequest::with_match_id(58494587)
.queue_single(&osu)
.await?;
// ...
Ok(())
}
