<p>This method consumes <code>self</code> as only one value may ever be sent on a oneshot
|
||
channel. It is not marked async because sending a message to an oneshot
|
||
channel never requires any form of waiting. Because of this, the <code>send</code>
|
||
method can be used in both synchronous and asynchronous code without
|
||
problems.</p>
|
||
<p>A successful send occurs when it is determined that the other end of the
|
||
channel has not hung up already. An unsuccessful send would be one where
|
||
the corresponding receiver has already been deallocated. Note that a
|
||
return value of <code>Err</code> means that the data will never be received, but
|
||
a return value of <code>Ok</code> does <em>not</em> mean that the data will be received.
|
||
It is possible for the corresponding receiver to hang up immediately
|
||
after this function returns <code>Ok</code>.</p>
