Enum TryRecvError 

pub enum TryRecvError {
    Closed,
    Empty,
    RemoteReceive(RecvError),
    RemoteConnect(ConnectError),
    RemoteListen(ListenerError),
}

An error occurred during trying to receive over an mpsc channel.

Variants

Closed

All channel senders have been dropped.

Empty

Currently no value is ready to receive, but values may still arrive in the future.

RemoteReceive(RecvError)

Receiving from a remote endpoint failed.

RemoteConnect(ConnectError)

Connecting a sent channel failed.

RemoteListen(ListenerError)

Listening for a connection from a received channel failed.

Implementations

impl TryRecvError

pub fn is_final(&self) -> bool

Returns whether the error is final, i.e. no further receive operation can succeed.

Trait Implementations

impl Clone for TryRecvError

fn clone(&self) -> TryRecvError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryRecvError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TryRecvError

fn deserialize<__D>( __deserializer: __D, ) -> Result<TryRecvError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TryRecvError

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

Formats the value using the given formatter.

impl Error for TryRecvError

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 Serialize for TryRecvError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<TryRecvError> for RecvError

type Error = TryRecvError

The type returned in the event of a conversion error.
