Struct transducers::Mapping

pub struct Mapping<'t, T: 't, U, F: Fn(U) -> T + 't> { /* fields omitted */ }

The mapping transducer that applies a function to every element.

Methods

impl<'f, T: 'f, U, F: Fn(U) -> T + 'f> Mapping<'f, T, U, F>

fn new(f: &'f F) -> Mapping<'f, T, U, F>

The mapping transducer that applies f to every element.

Trait Implementations

impl<'t, R: 't, T: 't, U, F: Fn(U) -> T + 't> Transducer<'t, R, T, U> for Mapping<'t, T, U, F>

type Step = MappingStep<'t, R, T, F>

The type of step that application of the transducer produces.

fn apply<Step: Fn(R, T) -> R + 't>(
    &self,
    step: Step
) -> MappingStep<'t, R, T, F>

Applies the transducer to the step function to obtain a new step function.
