Event
enum
enum EventA readiness event a {@see Watcher} asks for or reports.

Write | | The handle is writable. |
Error | | An error condition occurred on the handle. |
HangUp | | The peer hung up. |
ReadHangUp | | The peer closed its writing side. |
OneShot | | Watch mode: report the handle once. |
EdgeTriggered | | Watch mode: report changes of readiness instead of the level. |
