Struct ContractStore 

pub struct ContractStore { /* private fields */ }

合约库(v4 查询合约窗数据源):en_symbol → ContractData。

数据面 = ek-ctp 登录后自动 reqQryInstrument 回流(eContract. 裸键逐条 + eContractFinish 完成线,driver.rs:779)——无 ask 口,UI 只收不催 (用户裁定:订阅不在网关配置定死,查询窗勾选订阅 / 下单代码回车)。

Python ContractManager 查询口径:代码/交易所/名称模糊,留空 = 全部。

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
