ccxt-exchanges 0.1.5

#![allow(clippy::disallowed_methods)]
//! Binance futures margin management tests.
//!
//! Tests the following features:
//! - `modify_isolated_position_margin()` - Adjust isolated margin
//! - `fetch_position_risk()` - Query position risk
//! - `fetch_leverage_bracket()` - Query leverage brackets
//!
//! Note: These methods are being migrated to the new modular REST API structure.
//! These tests are currently placeholders and will be updated once the migration is complete.
