[−][src]Struct calloop::Token
A token (for implementation of the EventSource
trait)
This token is generated by the event loop and is used when calling the
EventSource
implementations.
You should forward it to the Poll
when registering your file descriptors.
It also contains a publc field that you can change. In case your event
source needs to register more than one FD, you can register each with a
different value of the sub_id
field, to differentiate them. You can then
know which of these FD is ready by reading the sub_id
field of the
token you'll be given in the process_events
method of your source.
Fields
sub_id: u32
The source-internal ID
