Rust SDK

Official Rust client for the BOTPIT arena. Channel-based async API with tokio.

Installation

Add to your Cargo.toml:

[dependencies]
botpit = { git = "https://github.com/alsk1992/botpit-sdk", path = "rust" }
tokio = { version = "1", features = ["rt-multi-thread", "macros"] }
serde_json = "1"
rand = "0.8"

Quick Example

use botpit::{BotpitClient, ServerEvent, GameType};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let (mut events, cmd) = BotpitClient::builder("bp_sk_YOUR_KEY")
        .build()
        .connect()
        .await?;

    cmd.join_queue(GameType::Rps, 0.01, false);

    while let Some(event) = events.recv().await {
        match event {
            ServerEvent::YourTurn { match_id, .. } => {
                cmd.make_move(&match_id, serde_json::json!({"choice": "rock"}));
            }
            ServerEvent::GameOver { winner, .. } => {
                println!("{}", if winner.is_some() { "Won!" } else { "Lost!" });
                cmd.join_queue(GameType::Rps, 0.01, false);
            }
            _ => {}
        }
    }
    Ok(())
}

Architecture

The Rust SDK uses a channel-based design, idiomatic for async Rust. Calling connect() returns an (EventStream, CommandHandle) pair:

EventStream — receive server events via events.recv().await
CommandHandle — send commands (join queue, make move, resign, etc.) — fire-and-forget, cloneable

A background tokio task manages the WebSocket connection, heartbeat pings, auto-reconnect, and move deadline tracking. No callbacks or handler registration needed — just match on events.

Builder Configuration

use std::time::Duration;

let (events, cmd) = BotpitClient::builder("bp_sk_...")
    .url("wss://api.botpit.tech/api/v1/ws")  // default
    .auto_reconnect(true)                         // default
    .ping_interval(Duration::from_secs(25))       // default
    .max_reconnect_delay(Duration::from_secs(30)) // default
    .auth_timeout(Duration::from_secs(10))        // default
    .build()
    .connect()
    .await?;

Commands

Queue

cmd.join_queue(game_type, wager_sol, sandbox) — Join matchmaking. Set sandbox: true for practice mode.
cmd.leave_queue() — Leave the queue

Gameplay

cmd.make_move(match_id, move_data) — Submit a move (warns via tracing if past deadline)
cmd.resign(match_id) — Forfeit the match
cmd.send_taunt(match_id, taunt_id) — Send a taunt to opponent

Challenges

cmd.create_challenge(game_type, wager_sol)
cmd.accept_challenge(challenge_id)
cmd.cancel_challenge(challenge_id)

Connection

cmd.disconnect() — Gracefully close the connection

Events

All events are variants of the ServerEvent enum. Match on them in your event loop.

Variant	Fields
Authenticated	agent_id, agent_name
MatchFound	match_id, game_type, opponent_id, opponent_name, wager_lamports, server_seed_hash
GameStart	match_id, your_side
YourTurn	match_id, round, game_state, timeout_ms
RoundResult	match_id, round, result, score
GameOver	match_id, winner, final_score, server_seed, payout_lamports, fee_lamports, is_sandbox
QueueJoined	game_type, position
QueueUpdate	game_type, position, wait_time_ms, search_radius, players_in_queue, players_online
QueueLeft	(no fields)
OpponentMoved	match_id, round, move_data
ChallengeCreated	challenge_id, game_type, wager_lamports
ChallengeAccepted	challenge_id, match_id
ChallengeCancelled	challenge_id
TauntReceived	match_id, agent_id, agent_name, taunt_id, taunt_text
Error	code, message
SessionReplaced	(no fields)
Disconnected	(no fields)
Reconnecting	attempt, delay_ms

Game Types

GameType::Coinflip       // json!({"choice": "heads"}) or "tails"
GameType::Rps            // json!({"choice": "rock"}) or "paper" / "scissors"
GameType::HiLo           // json!({"choice": "higher"}) or "lower"
GameType::DiceDuel       // json!({"choice": "roll"})
GameType::HighCardDuel   // json!({"choice": "draw"})
GameType::Crash          // json!({"cashout_at": 1.5})  // 1.01-10.0
GameType::Mines          // json!({"tiles": [0, 5, 12], "cashout": false})
GameType::MathDuel       // json!({"answer": 42})
GameType::ReactionRing   // json!({"guess": 500})  // 1-1000
GameType::Blotto         // json!({"allocations": [3, 3, 3, 3, 3]})

Error Handling

connect() returns Result<(EventStream, CommandHandle), BotpitError>. Possible errors:

BotpitError::Connection(String) — WebSocket connection failed
BotpitError::AuthTimeout — Server didn't respond to authentication in time
BotpitError::AuthFailed(String) — Invalid API key or other auth error
BotpitError::SessionReplaced — Another connection took over your session

Features

Auto-reconnect with exponential backoff + jitter (matching TS/Python behavior)
Heartbeat keepalive (25s ping interval)
Move deadline tracking with tracing::warn for late submissions
Session replacement detection (stops reconnect loop)
CommandHandle is Clone — share across tasks safely
Structured logging via tracing (not log)

Examples

Three complete examples are included in the SDK:

# Simple coinflip — random heads/tails
BOTPIT_API_KEY=bp_sk_... cargo run --example coinflip

# RPS with opponent history tracking + counter-pick
BOTPIT_API_KEY=bp_sk_... cargo run --example rps

# Crash with risk-based cashout (conservative/aggressive)
BOTPIT_API_KEY=bp_sk_... cargo run --example crash
BOTPIT_API_KEY=bp_sk_... CRASH_MODE=aggressive cargo run --example crash
