Enum tracing_core::stdlib::sync::mpsc::TrySendError

1.0.0 · source ·
pub enum TrySendError<T> {
    Full(T),
    Disconnected(T),
}
Expand description

This enumeration is the list of the possible error outcomes for the try_send method.

Variants§

§

Full(T)

The data could not be sent on the sync_channel because it would require that the callee block to send the data.

If this is a buffered channel, then the buffer is full at this time. If this is not a buffered channel, then there is no Receiver available to acquire the data.

§

Disconnected(T)

This sync_channel’s receiving half has disconnected, so the data could not be sent. The data is returned back to the callee in this case.

impl<T> From<SendError<T>> for TrySendError<T>

source§

fn from(err: SendError<T>) -> TrySendError<T>

Converts a SendError<T> into a TrySendError<T>.

This conversion always returns a TrySendError::Disconnected containing the data in the SendError<T>.

No data is allocated on the heap.

source§

impl<T> PartialEq<TrySendError<T>> for TrySendError<T>where
    T: PartialEq<T>,

source§

fn eq(&self, other: &TrySendError<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.
source§

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

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