Enum DeliveryError 

pub enum DeliveryError {
    MissingPort(&'static str),
    Database(DbError),
    Encode(String),
}

Why a whole drain pass cannot start.

Variants

MissingPort(&'static str)

A port the module requires is absent from this deployment.

Database(DbError)

The database refused a read or a write.

Encode(String)

The envelope could not be serialised. Cannot happen for a payload that parsed on the way in, but a serde error is not a panic.

impl Eq for DeliveryError

impl Error for DeliveryError

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
