Struct OrderEvent 

pub struct OrderEvent {
    pub price: Decimal,
    pub quantity_delta: u64,
    pub side: Side,
}

Represents an event published by the OrderBook when its state changes.

This event is consumed by downstream services (like MarketDepthCache) to update their own state without blocking the core order book operations.

Fields

price: Decimal

The exact price level where the change occurred

quantity_delta: u64

The change in quantity at this price level (positive for additions)

side: Side

Whether this event affects the bid or ask side

Trait Implementations

impl Clone for OrderEvent

fn clone(&self) -> OrderEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderEvent

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

Formats the value using the given formatter.

impl PartialEq for OrderEvent

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