Struct MainBrokerSnapshot 

pub struct MainBrokerSnapshot {
    pub main_brokers: Vec<u32>,
    pub connect_brokers: Vec<u32>,
    pub crypto_brokers: Vec<u32>,
}

MainBrokerageRsp 解析后的 snapshot, 用于 MainBrokerCache.

Fields

main_brokers: Vec<u32>

主推券商 (按 backend 下发顺序)

connect_brokers: Vec<u32>

主推 + 已开户 (建 broker channel 时用, 9419 主要应用)

v1.4.110 codex audit P3 #9: 当前 Rust daemon 不读此字段 — broker channel 建连仍走 auth_code_list (HTTP auth 拿到的) + CMD20176 (sanity check), 见 futu-backend::valid_brokers 模块文档. 保留此字段作 future fallback 数据源 (若 auth_code_list 滞后/失效, 可切到 9419 connect_brokers 作权威). codex 调研 12:02 增量 §B 列了 3 个数据源的语义差异.

crypto_brokers: Vec<u32>

数字货币主推券商 (按 backend 下发顺序, QOT default broker 解析关键)

Implementations

impl MainBrokerSnapshot

pub fn default_crypto_broker( &self, single_crypto_account_broker: Option<u32>, ) -> u32

C++ INNData_Trd_MainBrokerage::GetCryptoSupportedDefaultMainBroker() 等价 (line 70-123).

选择顺序:

1. 如果 caller 提供了已开户 crypto account 数 == 1, 直接用该 account 的 broker (caller 责任注入, 本 fn 不查 trd_cache).
2. crypto_brokers 第一个支持 crypto 的 main broker.
3. main_brokers 第一个支持 crypto 的 main broker.
4. 兜底 FALLBACK_DEFAULT_CRYPTO_BROKER (1007).
