Struct Filtering

Source 
pub struct Filtering<'p, T: 'p, P: Fn(&T) -> bool + 'p> { /* private fields */ }
Expand description

The filtering transducer that passes through elements that satisfy a predicate.

Implementations§

Source§

impl<'p, T, P: Fn(&T) -> bool + 'p> Filtering<'p, T, P>

Source

pub fn new(p: &'p P) -> Filtering<'p, T, P>

The filtering transducer passes through all elements for which the predicate p is true.

Trait Implementations§

Source§

impl<'p, R: 'p, T: 'p, P: Fn(&T) -> bool + 'p> Transducer<'p, R, T, T> for Filtering<'p, T, P>

Source§

type Step = FilteringStep<'p, R, T, P>

The type of step that application of the transducer produces.
Source§

fn apply<Step: Fn(R, T) -> R + 'p>( &self, step: Step, ) -> FilteringStep<'p, R, T, P>

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