Enum AckError 

#[non_exhaustive]
pub enum AckError {
    LeaseExpired,
    #[non_exhaustive]
    Rpc {
        source: Arc<Error>,
    },
    ShutdownBeforeAck,
    Shutdown(Box<dyn Error + Send + Sync>),
}

Represents an error that can occur when acking or nacking a message.

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.

LeaseExpired

The message’s lease expired before the client could ack or nack it.

The message has not been acked, and will be redelivered, maybe to another client.

#[non_exhaustive]

Rpc

The underlying RPC failed.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: Arc<Error>

The error returned by the service for the request.

ShutdownBeforeAck

Lease management shutdown before the client could acknowledge the message.

The client did not acknowledge the message. The service will redeliver message.

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

Error during shutdown.

The result of the operation is unknown. If you attempted to ack the message, the service may or may not redeliver it.

Trait Implementations

impl Debug for AckError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for AckError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for AckError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
