Struct chan::Receiver

pub struct Receiver<T>(_);

The receiving half of a channel.

Receivers can be cloned any number of times and sent to other threads.

Receivers also implement Sync, which means they can be shared among threads without cloning if the channels can be proven to outlive the execution of the threads.

When all receiving halves of a channel are dropped, no special action is taken. If the buffer in the channel is full, all sends will block indefinitely.

Methods

impl<T> Receiver<T>

fn recv(&self) -> Option<T>

Receive a value on this channel.

If this is an asnychronous channel, recv only blocks when the buffer is empty.

If this is a synchronous channel, recv only blocks when the buffer is empty.

If this is a rendezvous channel, recv blocks until a corresponding send sends a value.

For all channels, if the channel is closed and the buffer is empty, then recv always and immediately returns None. (If the buffer is non-empty on a closed channel, then values from the buffer are returned.)

Values are guaranteed to be received in the same order that they are sent.

This operation will never panic! but it can deadlock if the channel is never closed.

fn iter(&self) -> Iter<T>

Return an iterator for receiving values on this channel.

This iterator yields values (blocking if necessary) until the channel is closed.
