Enum SuotarErrorVariant 

Source 
pub enum SuotarErrorVariant {
    Unauthorized,
    MalformedRequest,
    RequestLevelError,
    ServiceTemporarilyUnavailable,
    ServerError,
    TransportNotDelivered,
    TransportUnknown,
    Deserialization,
}
Expand description

How a call to Suotar failed at the request level. Per-item failures are not errors: they come back inside a successful batch response.

Variants§

§

Unauthorized

Our credentials. Loud, and never attributed to the rows in the batch.

§

MalformedRequest

Our request. Loud, and never attributed to the rows in the batch.

§

RequestLevelError

Another 4xx carrying the documented { error: { code, message } } body.

§

ServiceTemporarilyUnavailable

Suotar’s 503 serviceTemporarilyUnavailable: an importer lookup failed before anything was written or sent.

§

ServerError

§

TransportNotDelivered

The connection itself failed, so the request provably never arrived.

§

TransportUnknown

The request left and the answer did not arrive. A timeout is this, not the above.

§

Deserialization

Suotar answered, and the answer was not a batch response.
