Enum RecvError 

pub enum RecvError {
    Closed,
    DowncastFailed(Box<dyn Any + Send>),
}

An error thrown while receiving from a dynamically typed tokio::sync::mpsc channel.

Variants

Closed

The channel was explicitly closed, or all senders were dropped, implicitly closing it.

DowncastFailed(Box<dyn Any + Send>)

A value received from the channel could not be cast into the correct expected type. This is always resultant from the other end of a channel failing to follow the session type of the channel.

Trait Implementations

impl Debug for RecvError

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

Formats the value using the given formatter.

impl Display for RecvError

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

Formats the value using the given formatter.

impl Error for RecvError

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<RecvError> for Error

fn from(err: RecvError) -> Self

Converts to this type from the input type.
