[crates-io-downloads-image]: https://img.shields.io/crates/d/topgg?style=flat-square
[crates-io-url]: https://crates.io/crates/topgg

The official Rust SDK for the [Top.gg API](https://docs.top.gg).

## Getting Started

Make sure to have a [Top.gg API](https://docs.top.gg) token handy. If not, then [view this tutorial on how to retrieve yours](https://github.com/top-gg/rust-sdk/assets/60427892/d2df5bd3-bc48-464c-b878-a04121727bff). After that, add the following line to the `dependencies` section of your `Cargo.toml`:

```toml
topgg = "1.4"
```

For more information, please read [the documentation](https://docs.rs/topgg)!

## Features

This library provides several feature flags that can be enabled/disabled in `Cargo.toml`. Such as:

- **`api`**: Interacting with the [Top.gg API](https://docs.top.gg) and accessing the `top.gg/api/*` endpoints. (enabled by default)
  - **`autoposter`**: Automating the process of periodically posting bot statistics to the [Top.gg API](https://docs.top.gg).
- **`webhook`**: Accessing the [serde deserializable](https://docs.rs/serde/latest/serde/de/trait.DeserializeOwned.html) `topgg::Vote` struct.
  - **`actix-web`**: Wrapper for working with the [actix-web](https://actix.rs/) web framework.
  - **`axum`**: Wrapper for working with the [axum](https://crates.io/crates/axum) web framework.
  - **`rocket`**: Wrapper for working with the [rocket](https://rocket.rs/) web framework.
  - **`warp`**: Wrapper for working with the [warp](https://crates.io/crates/warp) web framework.
- **`serenity`**: Extra helpers for working with [serenity](https://crates.io/crates/serenity) library (with bot caching disabled).
  - **`serenity-cached`**: Extra helpers for working with [serenity](https://crates.io/crates/serenity) library (with bot caching enabled).
- **`twilight`**: Extra helpers for working with [twilight](https://twilight.rs) library (with bot caching disabled).
  - **`twilight-cached`**: Extra helpers for working with [twilight](https://twilight.rs) library (with bot caching enabled).

## Examples

### Fetching a user from its Discord ID

```rust,no_run
use topgg::Client;

#[tokio::main]
async fn main() {
  let client = Client::new(env!("TOPGG_TOKEN").to_string());
  let user = client.get_user(661200758510977084).await.unwrap();
  
  assert_eq!(user.username, "null");
  assert_eq!(user.id, 661200758510977084);
  
  println!("{:?}", user);
}
```

### Posting your bot's statistics

```rust,no_run
use topgg::{Client, Stats};

#[tokio::main]
async fn main() {
  let client = Client::new(env!("TOPGG_TOKEN").to_string());

  let server_count = 12345;
  client
    .post_stats(Stats::from(server_count))
    .await
    .unwrap();
}
```

### Checking if a user has voted your bot

```rust,no_run
use topgg::Client;

#[tokio::main]
async fn main() {
  let client = Client::new(env!("TOPGG_TOKEN").to_string());

  if client.has_voted(661200758510977084).await.unwrap() {

  match vote.authenticate(env!("TOPGG_WEBHOOK_PASSWORD")) {
    Some(vote) => {
      println!("{:?}", vote);

      Ok("ok")
    }
    _ => Err(ErrorUnauthorized("401")),
  }
}

#[actix_web::main]
async fn main() -> io::Result<()> {
  HttpServer::new(|| App::new().service(index).service(webhook))
    .bind("127.0.0.1:8080")?
    .run()
    .await
}
```

  }
}

async fn index() -> &'static str {
  "Hello, World!"
}

#[tokio::main]
async fn main() {
  let state = Arc::new(MyVoteHandler {});

  let app = Router::new().route("/", get(index)).nest(
    "/webhook",
    topgg::axum::webhook(env!("TOPGG_WEBHOOK_PASSWORD").to_string(), Arc::clone(&state)),
  );

  let addr: SocketAddr = "127.0.0.1:8080".parse().unwrap();

  Server::bind(&addr)
    .serve(app.into_make_service())
    .await
    .unwrap();
}
```

  match vote.authenticate(env!("TOPGG_WEBHOOK_PASSWORD")) {
    Some(vote) => {
      println!("{:?}", vote);

      Status::Ok
    },
    _ => {
      println!("found an unauthorized attacker.");

      Status::Unauthorized
    }
  }
}

fn main() {
  rocket::ignite()
    .mount("/", routes![index, webhook])
    .launch();
}
```

### Writing a [warp](https://crates.io/crates/warp) webhook for listening to votes

In your `Cargo.toml`:

```toml

struct MyVoteHandler {}

#[async_trait::async_trait]
impl VoteHandler for MyVoteHandler {
  async fn voted(&self, vote: Vote) {
    println!("{:?}", vote);
  }
}

#[tokio::main]
async fn main() {
  let state = Arc::new(MyVoteHandler {});

  // POST /webhook
  let webhook = topgg::warp::webhook(
    "webhook",
    env!("TOPGG_WEBHOOK_PASSWORD").to_string(),
    Arc::clone(&state),
  );

  let routes = warp::get().map(|| "Hello, World!").or(webhook);

  let addr: SocketAddr = "127.0.0.1:8080".parse().unwrap();
