| <p><code>token: Token</code>: The caller picks a token to associate with the socket. |
| When <a href="struct.Poll.html#method.poll"><code>poll</code></a> returns an event for the handle, this token is included. |
| This allows the caller to map the event to its source. The token |
| associated with the <code>event::Source</code> can be changed at any time by |
| calling <a href="struct.Registry.html#method.reregister"><code>reregister</code></a>.</p> |
| <p>See documentation on <a href="struct.Token.html"><code>Token</code></a> for an example showing how to pick |
| <a href="struct.Token.html"><code>Token</code></a> values.</p> |
| <p><code>interest: Interest</code>: Specifies which operations <code>Poll</code> should monitor |
| for readiness. <code>Poll</code> will only return readiness events for operations |
| specified by this argument.</p> |
| <p>If a socket is registered with readable interest and the socket becomes |
| writable, no event will be returned from <a href="struct.Poll.html#method.poll"><code>poll</code></a>.</p> |
| <p>The readiness interest for an <code>event::Source</code> can be changed at any time |
| by calling <a href="struct.Registry.html#method.reregister"><code>reregister</code></a>.</p> |
| <h5 id="notes"><a href="#notes">Notes</a></h5> |
| <p>Callers must ensure that if a source being registered with a <code>Poll</code> |
| instance was previously registered with that <code>Poll</code> instance, then a |
| call to <a href="struct.Registry.html#method.deregister"><code>deregister</code></a> has already occurred. Consecutive calls to |
| <code>register</code> is unspecified behavior.</p> |
| <p>Unless otherwise specified, the caller should assume that once an event |
| source is registered with a <code>Poll</code> instance, it is bound to that <code>Poll</code> |
| instance for the lifetime of the event source. This remains true even |
| if the event source is deregistered from the poll instance using |
| <a href="struct.Registry.html#method.deregister"><code>deregister</code></a>.</p> |
