Enum OrderError 

#[non_exhaustive]
pub enum OrderError<AssetKey = AssetIndex, InstrumentKey = InstrumentIndex> {
    Connectivity(ConnectivityError),
    Rejected(ApiError<AssetKey, InstrumentKey>),
    UnsupportedOrderType(String),
}

Represents all errors that can be generated when cancelling or opening orders.

This is a subset of ClientError for order-specific operations. Use is_transient() to determine retry eligibility.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Connectivity(ConnectivityError)

Connectivity-based error (timeout, socket failure, exchange offline).

Transient — retry with backoff. See ConnectivityError for details.

Rejected(ApiError<AssetKey, InstrumentKey>)

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).

Implementations

impl<AssetKey, InstrumentKey> OrderError<AssetKey, InstrumentKey>

pub fn is_transient(&self) -> bool

Returns true if this error is likely transient and the operation may succeed if retried after a suitable backoff.

Transient errors

• Connectivity errors (timeout, socket, offline)
• Rejected(ApiError::RateLimit)

Non-transient errors

• Other Rejected errors (invalid instrument, insufficient balance, etc.)
