Type Alias UnindexedOrderError 

pub type UnindexedOrderError = OrderError<AssetNameExchange, InstrumentNameExchange>;

Type alias for a OrderError that is keyed on AssetNameExchange and InstrumentNameExchange (yet to be indexed).

Aliased Type

pub enum UnindexedOrderError {
    Connectivity(ConnectivityError),
    Rejected(ApiError<AssetNameExchange, InstrumentNameExchange>),
    UnsupportedOrderType(String),
    InvalidPrecision(PrecisionViolation),
}

Variants

Connectivity(ConnectivityError)

Connectivity-based error (timeout, socket failure, exchange offline), or a venue failure that leaves the order’s status unknown.

Transient — retry with backoff. See ConnectivityError for details. The order may or may not have reached the matching engine, so before resubmitting an open request, reconcile its state (open orders, fills); a blind retry can place it twice.

Rejected(ApiError<AssetNameExchange, InstrumentNameExchange>)

API-based error (rate limit, invalid instrument, order rejected, etc.).

Retry semantics depend on the specific ApiError variant. Only ApiError::RateLimit is transient; other variants are not.

UnsupportedOrderType(String)

The order type is not supported by this connector.

Non-transient — the connector does not support this order type (e.g., trailing stop orders on a connector that only supports market/limit).

InvalidPrecision(PrecisionViolation)

A quantity or price in the request has more precision than the venue accepts, so the client refused it without sending it.

Non-transient — change the request. A client that refuses this way never rounds a value itself, because rounding would place a different order than the one requested; it documents how to read the venue’s precision so the caller can round first.
