Type Alias UnindexedClientError 

pub type UnindexedClientError = ClientError<AssetNameExchange, InstrumentNameExchange>;

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

Aliased Type

pub enum UnindexedClientError {
    Connectivity(ConnectivityError),
    Api(ApiError<AssetNameExchange, InstrumentNameExchange>),
    TaskFailed(String),
    Internal(String),
    Truncated {
        fills_read: usize,
    },
    TruncatedSnapshot {
        limit: usize,
    },
}

Variants

Connectivity(ConnectivityError)

Connectivity based error.

eg/ Timeout.

Api(ApiError<AssetNameExchange, InstrumentNameExchange>)

API based error.

eg/ RateLimit.

TaskFailed(String)

A background task panicked or was cancelled during an operation.

This indicates a bug or unexpected runtime condition (e.g., a tokio spawn_blocking task panicked). The operation was not retried and the caller should treat this as non-recoverable, requiring operator attention.

Internal(String)

An opaque error from an upstream library that cannot be further classified.

This is a catch-all for errors that don’t fit into Self::Connectivity or Self::Api categories — typically because the upstream library (e.g., ibapi, binance-sdk) returns unstructured errors.

Conservatively treated as non-transient. If you encounter this error frequently, consider filing an issue to improve error classification.

Truncated

A bounded read of fills could not advance past its start: more fills share the span’s first moment than one call can read, so a read from the same start would stop at the same place.

ExecutionClient::fetch_trades returns it rather than a TradesRead whose resume could only loop. The fills it read are not returned. Callers should alert operators and reconcile the span another way.

Fields

fills_read: usize

How many fills the read returned before it stopped.

TruncatedSnapshot

Open orders snapshot was truncated at the API’s row limit.

Unlike Self::Truncated (which applies to paginated fill reads), this error indicates a single-request endpoint hit its maximum row count. Alpaca’s /v2/orders endpoint caps results at 500; accounts with more concurrent open orders will have an incomplete snapshot.

Callers should alert operators — an incomplete order snapshot can cause duplicate submissions, missed cancellations, or incorrect position sizing.

Fields

limit: usize

Maximum number of rows returned by the single-request endpoint.
