Struct Map 

pub struct Map<I, F> { /* private fields */ }

Trait Implementations

impl<B, I: BidirIterator, F> BidirIterator for Map<I, F>

where F: FnMut(I::Item) -> B,

type Item = B

fn next(&mut self) -> Option<B>

fn prev(&mut self) -> Option<B>

Examples

fn forward(&mut self) -> Forward<&mut Self>

where Self: Sized,

Create a forward-moving Iterator, starting at the current position. The forward iterator borrows the underlying bidirectional iterator.

fn forward_owned(self) -> Forward<Self>

where Self: Sized,

Create a forward-moving Iterator, starting at the current position. Like forward(), but the resulting iterator owns the underlying bidirectional iterator.

fn backward(&mut self) -> Backward<&mut Self>

where Self: Sized,

Create a backward-moving Iterator, starting at the current position.

fn backward_owned(self) -> Backward<Self>

where Self: Sized,

Create a backward-moving Iterator, starting at the current position. The resulting iterator owns the underlying bidir iterator.

fn filter<P>(self, predicate: P) -> Filter<Self, P>

where Self: Sized, P: FnMut(&Self::Item) -> bool,

Examples

fn map<B, F>(self, f: F) -> Map<Self, F>

where Self: Sized, F: FnMut(Self::Item) -> B,

Examples

fn filter_map<B, F>(self, f: F) -> FilterMap<Self, F>

where Self: Sized, F: FnMut(Self::Item) -> Option<B>,
