Enum SendError

#[non_exhaustive]
pub enum SendError<CE> {
    Channel(CE),
    Memquota(Error),
}

Error returned when trying to write to a Sender

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.

Channel(CE)

The underlying channel rejected the message

Memquota(Error)

The memory quota system prevented the send

NB: when the channel is torn down due to memory pressure, the inner receiver is also torn down. This means that this variant is not always reported: sending on the sender in this situation may give SendError::Channel instead.

Trait Implementations

impl<CE: Clone> Clone for SendError<CE>

fn clone(&self) -> SendError<CE>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<CE: Debug> Debug for SendError<CE>

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

Formats the value using the given formatter.

impl<CE> Display for SendError<CE>

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

Formats the value using the given formatter.

impl<CE> Error for SendError<CE>

where CE: Error + 'static, Self: Debug + Display,

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<CE> From<Error> for SendError<CE>

fn from(source: Error) -> Self

Converts to this type from the input type.
