pub struct CharIterator<'self> { priv string: &'self str, }
External iterator for a string's characters.
Use with the std::iterator
module.
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.
Prefix searches with a type followed by a colon (e.g.
fn:
) to restrict the search to a given type.
Accepted types are: fn
, mod
,
struct
(or str
), enum
,
trait
, typedef
(or
tdef
).
