Enum aws_smithy_runtime_api::client::waiters::error::WaiterError

#[non_exhaustive]
pub enum WaiterError<O, E> {
    ConstructionFailure(ConstructionFailure),
    ExceededMaxWait(ExceededMaxWait),
    FailureState(FailureState<O, E>),
    OperationFailed(OperationFailed<E>),
}

Available on crate feature client only.

An error occurred while waiting.

This error type is useful for distinguishing between the max wait time being exceeded, or some other failure occurring.

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.

ConstructionFailure(ConstructionFailure)

An error occurred during waiter initialization.

This can happen if the input/config is invalid.

ExceededMaxWait(ExceededMaxWait)

The maximum wait time was exceeded without completion.

FailureState(FailureState<O, E>)

Waiting ended in a failure state.

A failed waiter state can occur on a successful response from the server if, for example, that response indicates that the thing being waited for won’t succeed/finish.

A failure state error will only occur for successful or modeled error responses. Unmodeled error responses will never make it into this error case.

OperationFailed(OperationFailed<E>)

A polling operation failed while waiting.

This error will only occur for unmodeled errors. Modeled errors can potentially be handled by the waiter logic, and will therefore end up in WaiterError::FailureState.

Note: If retry is configured, this means that the operation failed after retrying the configured number of attempts.
