Trait nom::Consumer [−] [src]

pub trait Consumer<I, O, E, M> {
    fn handle(&mut self, input: Input<I>) -> &ConsumerState<O, E, M>;
    fn state(&self) -> &ConsumerState<O, E, M>;
}

The Consumer trait wraps a computation and its state

it depends on the input type I, the produced value's type O, the error type E, and the message type M

Required Methods

`fn handle(&mut self, input: Input<I>) -> &ConsumerState<O, E, M>`

implement handle for the current computation, returning the new state of the consumer

`fn state(&self) -> &ConsumerState<O, E, M>`

returns the current state

Implementors

impl<'a, R, S: Clone, T, E: Clone, M: Clone, F: Fn(S) -> T, C: Consumer<R, S, E, M>> Consumer<R, T, E, M> for MapConsumer<'a, C, R, S, T, E, M, F>
impl<'a, 'b, R, S: Clone, T: Clone, E: Clone, M: Clone, C1: Consumer<R, S, E, M>, C2: Consumer<S, T, E, M>> Consumer<R, T, E, M> for ChainConsumer<'a, 'b, C1, C2, R, S, T, E, M>
