Enum std::comm::TryRecvResult

pub enum TryRecvResult<T> {
    Empty,
    Disconnected,
    Data(T),
}

This enumeration is the list of the possible reasons that try_recv could not return data when called.

Variants

Empty

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

Disconnected

This channel's sending half has become disconnected, and there will never be any more data received on this channel

Data

The channel had some data and we successfully popped it

Trait Implementations

Derived Implementations

impl<T: Show> Show for TryRecvResult<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T: Clone> Clone for TryRecvResult<T>

fn clone(&self) -> TryRecvResult<T>

Returns a copy of the value. The contents of owned pointers are copied to maintain uniqueness, while the contents of managed pointers are not copied.

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

Perform copy-assignment from source.

a.clone_from(&b) is equivalent to a = b.clone() in functionality, but can be overridden to reuse the resources of a to avoid unnecessary allocations.

impl<T: Eq> Eq for TryRecvResult<T>

fn eq(&self, __arg_0: &TryRecvResult<T>) -> bool

fn ne(&self, __arg_0: &TryRecvResult<T>) -> bool
