Crate fyers_rs 

Idiomatic async Rust client for the documented Fyers broker APIs.

The crate is organized around a single FyersClient with typed accessors for auth, REST, and WebSocket surfaces. The market-data WebSocket talks the real Fyers V3 binary protocol (auth handshake, channel-mode set, channel resume, HSM-token-resolved subscribe, ack flow control) — see ws::DataSocketConnection and ws::data_protocol.

Quick start

use fyers_rs::FyersClient;

let client = FyersClient::builder()
    .client_id("APPID-100")
    .access_token("ACCESS_TOKEN")
    .build()?;

let _orders = client.orders();
let _market_data = client.market_data();
let _data_socket = client.data_socket();

REST and WebSocket APIs

REST services live under rest and typed request/response/event models live under models. WebSocket managers are exposed through ws.

Verification status

The market-data WebSocket and the profile/funds/holdings REST endpoints have been live-verified end-to-end. REST order placement, modification, and cancellation paths have never been live-fired against a real Fyers account — the URLs and payload shapes match the official Python SDK, but a round-trip live order has not yet been performed through this crate. See the README’s verification matrix and the per-module status notes.

Warning

This project is entirely AI-generated at this stage. It has not been independently audited or battle-tested. Review, test, and verify all behavior yourself before using it with real Fyers credentials, market data, or orders.
