Module signed_request 

Generic signed request builder for authenticated API requests.

This module provides a reusable infrastructure for building authenticated requests across different cryptocurrency exchanges. Each exchange implements the SigningStrategy trait to define its specific signing behavior.

Architecture

• SignedRequestBuilder: Generic builder handling parameter management and request execution
• SigningStrategy: Trait for exchange-specific signing (timestamp, signature, headers)
• HasHttpClient: Trait for exchanges that can execute HTTP requests
• SigningContext: Data structure containing all signing-related information

Example

// Exchange implements HasHttpClient and provides a SigningStrategy
let response = exchange
    .signed_request("/api/v3/account")
    .param("symbol", "BTCUSDT")
    .optional_param("limit", Some(100))
    .execute()
    .await?;
