Enum UndeliverableReason 

pub enum UndeliverableReason {
    Transport(TransportFailure),
    PortGone(PortGone),
}

Implementations

impl UndeliverableReason

pub fn is_transport(&self) -> bool

Returns true if this is a UndeliverableReason::Transport, otherwise false

pub fn as_transport_mut(&mut self) -> Option<&mut TransportFailure>

Optionally returns mutable references to the inner fields if this is a UndeliverableReason::Transport, otherwise None

pub fn as_transport(&self) -> Option<&TransportFailure>

Optionally returns references to the inner fields if this is a UndeliverableReason::Transport, otherwise None

pub fn into_transport(self) -> Result<TransportFailure, Self>

Returns the inner fields if this is a UndeliverableReason::Transport, otherwise returns back the enum in the Err case of the result

pub fn is_port_gone(&self) -> bool

Returns true if this is a UndeliverableReason::PortGone, otherwise false

pub fn as_port_gone_mut(&mut self) -> Option<&mut PortGone>

Optionally returns mutable references to the inner fields if this is a UndeliverableReason::PortGone, otherwise None

pub fn as_port_gone(&self) -> Option<&PortGone>

Optionally returns references to the inner fields if this is a UndeliverableReason::PortGone, otherwise None

pub fn into_port_gone(self) -> Result<PortGone, Self>

Returns the inner fields if this is a UndeliverableReason::PortGone, otherwise returns back the enum in the Err case of the result

Trait Implementations

impl Clone for UndeliverableReason

fn clone(&self) -> UndeliverableReason

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UndeliverableReason

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UndeliverableReason

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

impl Error for UndeliverableReason

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PortGone> for UndeliverableReason

fn from(source: PortGone) -> Self

Converts to this type from the input type.

impl From<TransportFailure> for UndeliverableReason

fn from(source: TransportFailure) -> Self

Converts to this type from the input type.

impl From<UndeliverableReason> for DeliveryFailureKind

fn from(source: UndeliverableReason) -> Self

Converts to this type from the input type.

impl PartialEq for UndeliverableReason

fn eq(&self, other: &UndeliverableReason) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UndeliverableReason

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
