drm-core

Core traits, models, and errors for the dr-manhattan prediction market SDK.

Overview

drm-core provides the foundational components for building prediction market integrations:

• Exchange trait: Unified async interface for all prediction market operations
• Models: Market, Order, Position, Orderbook, and more
• WebSocket trait: Real-time orderbook and trade streaming
• Strategy trait: Framework for building trading strategies
• Error types: Comprehensive error hierarchy (DrmError)

Installation

[dependencies]
drm-core = "0.1"

Usage

This crate is typically used as a dependency by exchange implementations (drm-exchange-polymarket, drm-exchange-limitless, drm-exchange-opinion).

use drm_core::{Exchange, Market, Order, OrderSide, DrmError};

// The Exchange trait defines the unified API
#[async_trait]
pub trait Exchange: Send + Sync {
    fn id(&self) -> &'static str;
    fn name(&self) -> &'static str;
    
    async fn fetch_markets(&self, params: Option<FetchMarketsParams>) -> Result<Vec<Market>, DrmError>;
    async fn fetch_market(&self, market_id: &str) -> Result<Market, DrmError>;
    async fn create_order(&self, ...) -> Result<Order, DrmError>;
    // ... more methods
}

Models

Features

• Async-first: Built on tokio for high-performance async operations
• Type-safe: Leverage Rust's type system for compile-time safety
• Serde support: All models are serializable/deserializable
