CCRXT

Rust wrappers around cryptocurrency exchange APIs with a focus on low-latency, high-frequency trading applications.

Note: This library is currently in development. The Crates.io and Documentation badges will become functional when the library is published.

Exchange Features

• ✅ Complete: Full implementation with comprehensive API coverage
• 🚧 In Progress: Basic infrastructure in place, endpoints being added

Implementation Status

• REST: Public and private REST API endpoints with rate limiting and error handling
• WebSocket: Real-time data feeds and streaming APIs
• ✅: Fully implemented and tested
• 🚧: In development
• ❌: Not yet implemented

Testing Status

• Public Tests: Integration tests for public API endpoints (market data, instrument info, etc.)
• Private Tests: Integration tests for private API endpoints (account data, trading operations)
• ✅: Tests implemented and passing
• ❌: Tests not yet implemented

Venue Documentation

Each venue includes a README with:

• Links to the official API documentation
• Authentication requirements
• List of implemented endpoints

See the venues directory for details.

Design Principles

1. All venues implement low latency APIs. If WebSocket is available, it is preferred over REST.
2. Venue rate limiting is implemented exactly as specified by the exchange.
3. Wrappers around endpoints are pure; no helper or fix-up logic is included.
4. All WebSocket clients implement the common WebSocket trait.
5. File and module structure follows strict conventions for maintainability and clarity.

Rust Version Policy

This project targets ONLY the latest stable Rust release.

• rust-toolchain.toml pins the toolchain to stable so builds automatically track the newest stable once installed.
• Cargo.toml rust-version field is updated to the most recent stable (currently 1.89.0) and will be bumped promptly after each stable release.
• No nightly feature gates (#![feature(...)]) are permitted.
• Patterns that previously required nightly (e.g., let_chains before stabilization in 1.88) may now use the stable syntax where it improves clarity.
• CI enforces these rules via a verification script.

If you need a feature that is only on nightly, open an issue to discuss alternatives before proposing nightly usage.

Testing

• Unit tests are colocated with the code they test and do not require credentials or network access.
• Integration tests are in the tests/ directory and cover real API interactions (where supported).

Examples

• Example code for each venue is in venues/examples/.
• Examples are self-contained and demonstrate usage of public APIs, with clear instructions for credentials if
