Struct mio_st::event::EventedId

#[repr(transparent)]
pub struct EventedId(pub usize);

Associates readiness notifications with Evented handles.

EventedId is used as an argument to Poller.register and Poller.reregister and is used to associate an Event with an Evented handle.

See Poller for more documentation on polling.

Uniqueness of EventedId

EventedId does not have to be unique within a Poller instance, it is purely a tool for the user of Poller to associate an Event with an Evented handle. It is advised for example to use the same EventedId for say a TcpStream and any related timeout or deadline for the same connection. The EventedID is effectively opaque to Poller.
