Lavalink

twilight-lavalink is a client for Lavalink for use with model events from the gateway.

It includes support for managing multiple nodes, a player manager for conveniently using players to send events and retrieve information for each guild, and an HTTP module for creating requests using the http crate and providing models to deserialize their responses.

Features

HTTP Support

The http-support feature adds types for creating requests and deserializing response bodies of Lavalink's HTTP routes via the http crate.

This is enabled by default.

TLS

twilight-lavalink has features to enable async-tungstenite's TLS features. These features are mutually exclusive.

rustls is enabled by default.

Native

The native feature enables async-tungstenite's tokio-native-tls feature. This will use native TLS support, for example OpenSSL on Linux.

RusTLS

The rustls feature enables async-tungstenite's tokio-rustls which uses the RusTLS crate as the TLS backend.

This is enabled by default.

Examples

Create a client, add a node, and give events to the client to process events:

use futures::StreamExt;
use std::{
    env,
    error::Error,
    net::SocketAddr,
    str::FromStr,
};
use twilight_gateway::{Intents, Shard};
use twilight_http::Client as HttpClient;
use twilight_lavalink::Lavalink;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error + Send + Sync + 'static>> {
    let token = env::var("DISCORD_TOKEN")?;
    let lavalink_host = SocketAddr::from_str(&env::var("LAVALINK_HOST")?)?;
    let lavalink_auth = env::var("LAVALINK_AUTHORIZATION")?;
    let shard_count = 1_u64;

    let http = HttpClient::new(token.clone());
    let user_id = http.current_user().exec().await?.model().await?.id;

    let lavalink = Lavalink::new(user_id, shard_count);
    lavalink.add(lavalink_host, lavalink_auth).await?;

    let intents = Intents::GUILD_MESSAGES | Intents::GUILD_VOICE_STATES;
    let (shard, mut events) = Shard::new(token, intents);

    shard.start().await?;

    while let Some(event) = events.next().await {
        lavalink.process(&event).await?;
    }

    Ok(())
}
