Trait gui::EventChain

pub trait EventChain<ED> {
    fn chain<ES>(self, event: ES) -> ChainEvent<ED>
    where
        ES: Into<ChainEvent<ED>>;
    fn chain_opt<ES>(self, event: Option<ES>) -> ChainEvent<ED>
    where
        ES: Into<ChainEvent<ED>>;
}

A trait for chaining of events.

Required methods

fn chain<ES>(self, event: ES) -> ChainEvent<ED> where
    ES: Into<ChainEvent<ED>>, 

Chain together two events.

The given event will effectively be appended to the current one and, hence, be handled after the first one got processed.

fn chain_opt<ES>(self, event: Option<ES>) -> ChainEvent<ED> where
    ES: Into<ChainEvent<ED>>, 

Chain together an event with an optional event.

This method returns the chain of the first event with the second one, if present, or otherwise just returns the first one.
