Trait Implementations

impl<S, P> Source for FilterQuadSource<S, P>

where S: QuadSource, P: FnMut(&S::Item<'_>) -> bool,

type Item<'x> = <S as Source>::Item<'x>

The type of items this source yields.

type Error = <S as Source>::Error

The type of errors produced by this source.

fn try_for_some_item<E, F>( &mut self, f: F, ) -> StreamResult<bool, Self::Error, E>

where E: Error + Send + Sync + 'static, F: FnMut(Self::Item<'_>) -> Result<(), E>,

Call f for some item(s) (possibly zero) from this source, if any.

fn size_hint_items(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the source.

fn try_for_each_item<F, E>(&mut self, f: F) -> StreamResult<(), Self::Error, E>

where F: FnMut(Self::Item<'_>) -> Result<(), E>, E: Error + Send + Sync + 'static,

Call f for all items from this source.

fn for_some_item<F>(&mut self, f: F) -> Result<bool, Self::Error>

where F: FnMut(Self::Item<'_>),

Call f for some item(s) (possibly zero) from this source, if any.

fn for_each_item<F>(&mut self, f: F) -> Result<(), Self::Error>

where F: FnMut(Self::Item<'_>),

Call f for all items from this source.

fn filter_items<F>(self, predicate: F) -> FilterSource<Self, F>

where Self: Sized, F: FnMut(&Self::Item<'_>) -> bool,

Returns a source which uses predicate to determine if an item should be yielded.

fn filter_map_items<F, T>(self, filter_map: F) -> FilterMapSource<Self, F>

where Self: Sized, F: FnMut(Self::Item<'_>) -> Option<T>,

Returns a source that both filters and maps.

fn map_items<F, T>(self, map: F) -> MapSource<Self, F>

where Self: Sized, F: FnMut(Self::Item<'_>) -> T,

Returns a source which yield the result of map for each Item.
