v1.4.106 codex 0219 Finding 1+4: trade-write resolution snapshot.

用于 ModifyOrder / CancelOrder handler 把 cached order 字段一次性 拿出来构造 backend req. 不在 hot path 改 CachedOrder, 而是返一个 只读 snapshot 防 caller mutate cache.

字段 1:1 映射 backend OrderReplaceReq / OrderCancelReq 必填项 + modify validation 用到的 (order_type / trd_side / qty / price / order_status).

Fields

backend_order_id: String

= backend szOrderID (alphanumeric 字符串, 服务端真实 id).

order_version: i32

= backend Order.version.

exchange_code: i32

= backend Order.exchange_code (期货所属交易所代码, e.g. NN_QotMarket).

exchange: String

= backend Order.exchange (股票所属交易所字符串, e.g. “SEHK”).

security_type: i32

= backend Order.security_type (1=COMMON, 2=OPTION, 4=FUTURES, 5=BOND).

order_type: i32

FTAPI OrderType (modify validation 按原 order_type 决定 price / aux_price / trail* 是否必填).

trd_side: i32

FTAPI TrdSide (1=Buy / 2=Sell / 3=SellShort / 4=BuyBack). trailing modify 计算 sign 用.

order_status: i32

FTAPI OrderStatus (IsNotSupportOrderOp 检查用).

trd_market: Option<i32>

FTAPI TrdMarket (modify validation 中 sec_type futures 路径用).

qty: f64

FTAPI Order.qty (历史值, 仅 modify validation 引用).

price: f64

FTAPI Order.price (历史值, 仅 modify validation 引用).

code: String

FTAPI Order.code (用于错误提示 + log 关联).

is_stub: bool

PlaceOrder stub 标记. PlaceOrder ack 时插入的 stub is_stub=true + order_version=0. ModifyOrder 按 C++ 本地回显订单 nVersion=-1 映射为 backend wire u32::MAX; CancelOrder 不依赖 order_version.

is_pending_broker_confirm: bool

PlaceOrder stub 是否仍在等待 broker/backend 权威确认.

Real write handlers use this to avoid reporting success against a local optimistic echo when the authoritative order list has not accepted the order yet.

Implementations

impl CachedOrderSnapshot

pub fn from_order(o: &CachedOrder) -> Self

从 CachedOrder 抽出 trade-write resolution 用到的字段子集.

Trait Implementations

impl Clone for CachedOrderSnapshot

fn clone(&self) -> CachedOrderSnapshot

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CachedOrderSnapshot

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CachedOrderSnapshot

fn default() -> CachedOrderSnapshot

Returns the “default value” for a type.

impl PartialEq for CachedOrderSnapshot

fn eq(&self, other: &CachedOrderSnapshot) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
