Trait Implementations

impl<'self> Clone for CharIterator<'self>

fn clone(&self) -> CharIterator<'self>

Returns a copy of the value. The contents of owned pointers are copied to maintain uniqueness, while the contents of managed pointers are not copied.

impl<'self> Iterator<char> for CharIterator<'self>

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

Advance the iterator and return the next value. Return None when the end is reached.

fn size_hint(&self) -> (uint, Option<uint>)

Return a lower bound and upper bound on the remaining length of the iterator.

The common use case for the estimate is pre-allocating space to store the results.

impl<'self> DoubleEndedIterator<char> for CharIterator<'self>

fn next_back(&mut self) -> Option<char>

Yield an element from the end of the range, returning None if the range is empty.
