Struct calloop::Token

pub struct Token { /* fields omitted */ }

A token (for implementation of the EventSource trait)

This token is produced by the TokenFactory and is used when calling the EventSource implementations to process event, in order to identify which sub-source produced them.

You should forward it to the Poll when registering your file descriptors.

Implementations

impl Token

pub fn invalid() -> Token

Produces an invalid Token, that is not recognized by the event loop.

Can be used as a placeholder to avoid Option<Token>

pub fn is_invalid(self) -> bool

Check if this token is the invalid token

pub fn with_sub_id(self, sub_id: u32) -> Token

Provide a copy of the Token with the given sub_id.
