ProductClasses

Struct ProductClasses 

Source
pub struct ProductClasses(pub Vec<String>);
Expand description

网关收录的产品类白名单(CTP 单字符码 THOST_FTDC_PC_*)。

语义(D-PC-FILTER,DESIGN.md):查询侧不过滤(原稿 reqQryInstrument({}) 全量, 且实测三个查询口都无法按类型过滤),收录侧严格丢弃 —— 不在名单内的合约行 既不进共享合约表,也不上抛 eContract。

空名单绝不等于「全丢」:一律回落默认(期货)。理由不是便利,是守卫 —— contracts 为空会让持仓查询整条被跳过(driver.rs 的 contracts.is_empty() 守卫), 一次误配置就把持仓数据关掉。

Implementations§

Source§

impl ProductClasses

Source

pub fn default_classes() -> Vec<String>

默认勾选:只有期货。

Source

pub fn normalize(&self) -> Vec<String>

归一化:去首尾空白、去重、丢弃非法码(CTP 产品类码是单字符), 结果为空则回落 ProductClasses::default_classes。返回有序去重表。

Source

pub fn accepts(&self, product_class: &str) -> bool

该产品类码是否收录。
