[][src]Struct collect_result::SizeHintedIter

pub struct SizeHintedIter<I> {
    pub lower: usize,
    pub upper: Option<usize>,
    // some fields omitted

Used to override the output of Iterator::size_hint of an iterator


lower: usize

The lower bound to pretend to have

upper: Option<usize>

The upper bound to pretend to have


impl<I: Iterator> SizeHintedIter<I>[src]

pub fn new(inner: I) -> Self[src]

Sets the bounds from the given iterator's Iterator::size_hint.

impl<I> SizeHintedIter<I>[src]

pub fn with_bounds(inner: I, lower: usize, upper: Option<usize>) -> Self[src]

Sets the bounds to the given arguments

pub fn into_inner(self) -> I[src]

Turns self into the inner iterator
