Rust

The Rivet Rust client provides a way to connect to and interact with actors from Rust applications.

Quickstart

Installation

Add RivetKit client to your Cargo.toml:

[dependencies]
rivetkit-client = "0.1.0"

Connect to your Actors

Make sure you have a running Rivet actor server to connect to. You can follow the Node.js & Bun Quickstart to set up a simple actor server.

use rivetkit_client::{Client, EncodingKind, GetOrCreateOptions, TransportKind};
use serde_json::json;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Create a client connected to your RivetKit manager
    let client = Client::new(
        "http://localhost:8080",
        TransportKind::Sse,
        EncodingKind::Json
    );

    // Connect to a chat room actor
    let chat_room = client.get_or_create(
        "chat-room",
        ["keys-here"].into(),
        GetOrCreateOptions::default()
    )?.connect();
    
    // Listen for new messages
    chat_room.on_event("newMessage", |args| {
        let username = args[0].as_str().unwrap();
        let message = args[1].as_str().unwrap();
        println!("Message from {}: {}", username, message);
    }).await;

    // Send message to room
    chat_room.action("sendMessage", vec![
        json!("william"),
        json!("All the world's a stage.")
    ]).await?;

    // When finished
    client.disconnect();

    Ok(())
}

Rust

Run your client

In a separate terminal, run your client code:

cargo run
