Trait domafic::processors::ListenerProcessor
[−]
[src]
pub trait ListenerProcessor<'a, Message> {
type Acc;
type Error;
fn get_processor<T: Listener<Message>>(
) -> fn(_: &mut Self::Acc, _: &'a T) -> Result<(), Self::Error>;
}ListenerProcessors are used to iterate over Listenerss which may or may not be the same
type. Implementations of this trait resemble traditional fold functions, modifying an
accumulator (of type Acc) and returning an error as necessary.
Associated Types
type Acc
Type of the accumulator updated by get_processor
type Error
Type of error returned by failed calls to get_processor
Required Methods
fn get_processor<T: Listener<Message>>(
) -> fn(_: &mut Self::Acc, _: &'a T) -> Result<(), Self::Error>
) -> fn(_: &mut Self::Acc, _: &'a T) -> Result<(), Self::Error>
Returns a folding function capable of processing elements of type T: DomNode.
