Discord Client Gateway

A high-level Rust implementation of the Discord gateway, designed to provide a robust and efficient client-side connection to Discord's real-time WebSocket API.

This crate offers a seamless integration for Discord bot developers, featuring:

• Zlib-stream decompression support for Discord's compressed payloads
• TLS impersonation and HTTP/2 (H2) mimicing of Chrome to avoid detection
• Automatic heartbeat with sequence number handling
• Efficient handling of Discord's WebSocket events
• Automatic shard management for scalable bot implementations
• Reconnect and resume support

Whether you're building a simple bot or a complete Discord client reimplementation, this crate provides the tools you need to establish and maintain a reliable connection to Discord's gateway.

Key Features

• High-level API
• Automatic reconnection
• Event dispatching
• Guilds subscribing

Usage

Dependencies

Add this crate to your Cargo.toml:

[dependencies]
discord_client_gateway = "0.1.0"

Creating a client

let token = "CLIENT_TOKEN".to_string();
let capabilities = 53607934; // Best if you want to receive all events
let client_build_nubmer = 402402; // You should always use the latest build number
// you can also fetch the build number from the crate `discord_client_rest`

let mut client = GatewayClient::connect(token, capabilities, client_build_nubmer)
    .await
    .unwrap();

Receive events

loop {
    let event = client.next_event().await.unwrap();
    println!("{}", event);
    // Print the new messages content
    if let Event::MessageCreate(message_create) = event {
        let centent = message_create.message.content.unwrap_or("No content".to_string());
        println!("Message: {}", content);
    }
}

Subscribe to guilds

This example shows how to subscribe to all guilds after receiving the Ready event.

You can just subscribe to the guilds you want to receive events from by giving the guild ids to the bulk_guild_subscribe method.

let event = client.next_event().await.unwrap();
println!("{}", event);

if let Event::Ready(ready) = event {
    let mut ids: Vec<u64> = Vec::new();
    let guilds = ready.guilds;
    for guild in guilds {
        let guild_id = guild.id;
        ids.push(guild_id);
    }

    client.bulk_guild_subscribe(ids).await.unwrap();
}
