Enum sp_std::sync::mpsc::TryRecvError

1.0.0 · source · [−]

pub enum TryRecvError {
    Empty,
    Disconnected,
}

Expand description

This enumeration is the list of the possible reasons that try_recv could not return data when called. This can occur with both a channel and a sync_channel.

Variants

`Empty`

This channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.

`Disconnected`

The channel’s sending half has become disconnected, and there will never be any more data received on it.

impl From<RecvError> for TryRecvError

source

pub fn from(err: RecvError) -> TryRecvError

Converts a RecvError into a TryRecvError.

This conversion always returns TryRecvError::Disconnected.

No data is allocated on the heap.

pub fn eq(&self, other: &TryRecvError) -> bool

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

source

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

This method tests for !=.
