Struct QotStockKey 

pub struct QotStockKey {
    pub stock_id: u64,
    pub broker_id: Option<NonZeroU32>,
}

QOT broker-aware stock 唯一识别.

对齐 C++ NNProtoCenter_Define_StockKey.h::StockKey:

• stock_id = C++ nStockID
• broker_id = Some(N) ⟺ C++ m_hasBroker = true && enBrokerID = N
• broker_id = None ⟺ C++ m_hasBroker = false

注意 broker_id 不接受 0 (C++ 语义: 0 = NN_BrokerID_Unknown = no-broker).

Fields

stock_id: u64

broker_id: Option<NonZeroU32>

Implementations

impl QotStockKey

pub const fn no_broker(stock_id: u64) -> Self

不带 broker 的 stock key (C++ StockKey(stockID)).

pub fn with_broker(stock_id: u64, broker_id: u32) -> Option<Self>

带 broker 的 stock key (C++ StockKey(stockID, brokerID)).

broker_id = 0 不接受 (C++ NN_BrokerID_Unknown 走 no-broker path). 返 None 时, caller 应该改用 no_broker(stock_id).

pub fn from_broker_id_or_no_broker(stock_id: u64, broker_id: u32) -> Self

从 u32 broker_id 安全构造 — 0 自动降级到 no-broker.

等价 C++ StockKey(stockID, brokerID == NN_BrokerID_Unknown ? no-broker : with broker).

pub fn has_broker(&self) -> bool

C++ HasBroker() 等价.

pub fn broker_id_or_zero(&self) -> u32

C++ GetBrokerID() 等价 (返 raw u32, no-broker 返 0).

Trait Implementations

impl Clone for QotStockKey

fn clone(&self) -> QotStockKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QotStockKey

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

Formats the value using the given formatter.

impl Display for QotStockKey

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

内部 cache key 编码: "{stock_id}" (no-broker) 或 "{stock_id}@b{broker_id}".

仅供 cache key / log 使用; 绝不直接暴露到 public Security 字段.

impl Hash for QotStockKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QotStockKey

fn cmp(&self, other: &QotStockKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for QotStockKey

fn eq(&self, other: &QotStockKey) -> 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.

impl PartialOrd for QotStockKey

fn partial_cmp(&self, other: &QotStockKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
