Error type for order book operations.

Variants

OrderAlreadyExists

Attempted to add an order that already exists in the book.

Fields

order_id: OrderId

existing_price: UD64

OrderNotFound

Attempted to update or remove an order that doesn’t exist.

Fields

order_id: OrderId

OrderNotAtExpectedLevel

Order exists in index but not found at the expected price level. This indicates internal inconsistency.

Fields

order_id: OrderId

expected_price: UD64

side: OrderSide

OrderIdMismatch

Attempted to update an order but the new order has a different ID.

Fields

expected: OrderId

actual: OrderId

InvalidOrderSize

Order has zero or negative size.

Fields

order_id: OrderId

size: UD64

InvalidOrderPrice

Order has zero price.

Fields

order_id: OrderId

price: UD64

LevelNotFound

Expected price level not found. This indicates internal inconsistency.

Fields

price: UD64

side: OrderSide

DanglingOrderReference

Order references another order that doesn’t exist in the snapshot. This indicates data inconsistency.

Fields

order_id: OrderId

referenced_id: OrderId

pointer: &'static str
