Module signed_request 

Signed request builder for Binance API.

This module provides a builder pattern for creating authenticated Binance API requests, encapsulating the common signing workflow used across all authenticated endpoints.

Overview

The SignedRequestBuilder eliminates code duplication by centralizing:

• Credential validation
• Timestamp generation
• Parameter signing with HMAC-SHA256
• Authentication header injection
• HTTP request execution

Example

let binance = Binance::new(ExchangeConfig::default())?;

// Simple GET request
let data = binance.signed_request("/api/v3/account")
    .execute()
    .await?;

// POST request with parameters
let data = binance.signed_request("/api/v3/order")
    .method(HttpMethod::Post)
    .param("symbol", "BTCUSDT")
    .param("side", "BUY")
    .param("type", "MARKET")
    .param("quantity", "0.001")
    .execute()
    .await?;
