Enum thingbuf::mpsc::errors::TrySendError

#[non_exhaustive]
pub enum TrySendError<T = ()> {
    Full(T),
    Closed(T),
}

Error returned by the Sender::try_send or Sender::try_send_ref (and StaticSender::try_send/StaticSender::try_send_ref) methods.

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.

Full(T)

The data could not be sent on the channel because the channel is currently full and sending would require waiting for capacity.

Closed(T)

The data could not be sent because the Receiver half of the channel has been dropped.

Implementations

impl<T> TrySendError<T>

pub fn is_full(&self) -> bool

Returns true if this error was returned because the channel was at capacity.

pub fn is_closed(&self) -> bool

Returns true if this error was returned because the channel has closed (e.g. the Receiver end has been dropped).

If this returns true, no future try_send or send operation on this channel will succeed.

pub fn into_inner(self) -> T

Unwraps the inner T value held by this error.

This method allows recovering the original message when sending to a channel has failed.
