Struct IterSource 

pub struct IterSource<I: Iterator> { /* private fields */ }

Source adapter over any IntoIterator.

Example

use pipe_io::source::{IterSource, Source};

let mut s = IterSource::new(vec![1, 2, 3]);
assert_eq!(s.pull().unwrap(), Some(1));
assert_eq!(s.pull().unwrap(), Some(2));
assert_eq!(s.pull().unwrap(), Some(3));
assert_eq!(s.pull().unwrap(), None);

Implementations

impl<I> IterSource<I>

where I: Iterator,

pub fn new<II>(into_iter: II) -> Self

where II: IntoIterator<IntoIter = I>,

Wrap an iterator into a source.

Trait Implementations

impl<I> Source for IterSource<I>

where I: Iterator,

type Item = <I as Iterator>::Item

Type of item produced.

type Error = Infallible

Error type the source can return.

fn pull(&mut self) -> Result<Option<Self::Item>, Self::Error>

Pull the next item.

fn close(&mut self) -> Result<(), Self::Error>

Close the source. Default impl does nothing.
