Enum WorkflowQueryError 

#[non_exhaustive]
pub enum WorkflowQueryError {
    NotFound(Status),
    Rejected(QueryRejected),
    PayloadConversion(PayloadConversionError),
    Rpc(Status),
    Other(Box<dyn Error + Send + Sync>),
}

Errors returned by query operations on crate::WorkflowHandle.

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.

NotFound(Status)

The workflow was not found.

Rejected(QueryRejected)

The query was rejected based on the rejection condition.

PayloadConversion(PayloadConversionError)

Error serializing input or deserializing output.

Rpc(Status)

An uncategorized RPC error from the server.

Other(Box<dyn Error + Send + Sync>)

Other errors.
