Struct calloop::Token

pub struct Token {
    pub sub_id: u32,
    // some fields omitted
}

A Token for registration

This token is given to you by the event loop, and 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
