Enum CurrencyValidation 

pub enum CurrencyValidation {
    Ok,
    Missing {
        broker_label: &'static str,
        supported_label_list: Vec<&'static str>,
    },
    Unsupported {
        broker_label: &'static str,
        supported_label_list: Vec<&'static str>,
    },
    Unknown,
}

Layer A 校验结果 (用 enum 让 caller 区分四种状态)

Variants

Ok

requested currency 在 broker supported set 内 → OK 发 backend. SingleCurrency 缺 currency 也归 Ok (跟 C++ legacy 分支一致).

Missing

v1.4.106 Finding F1: Futures / Universal 账户必传 currency, 未传 → loud reject (对齐 C++ CheckReqParams_GetFunds: if (!c2s.has_currency()) return false;). SingleCurrency 缺 currency 不进此分支, 仍归 Ok.

Fields

broker_label: &'static str

supported_label_list: Vec<&'static str>

Unsupported

requested currency 不在 set 内 → 立即 reject (不发 backend) 含 broker 标签 + supported list 用于 error message

Fields

broker_label: &'static str

supported_label_list: Vec<&'static str>

Unknown

无法判断 (security_firm=None / cache miss / unknown broker) — 不 hard reject, 让 backend 决定. 仍记录 hint 用于日志.
