tesser-broker

Exchange-agnostic traits that define how the rest of the system talks to brokers.

Overview

• Declares interfaces like MarketStream, ExecutionClient, HistoricalData, EventPublisher, and SignalBus.
• Provides the BrokerError hierarchy used for consistent error handling across connectors.
• No concrete exchange logic lives here—connectors implement these traits.

Implementing a Connector

1. Depend on tesser-broker and tesser-core.
2. Implement the necessary traits (ExecutionClient, MarketStream, etc.).
3. Map transport or exchange errors into BrokerErrorKind so upstream crates can react uniformly.

Tests

cargo test -p tesser-broker
