pub struct TreeMapRevIterator<'self, K, V> {
priv iter: TreeMapIterator<'self, K, V>,
}Lazy backward iterator over a map
impl<'self, K, V> std::iter::Iterator for TreeMapRevIterator<'self, K, V>fn next(&mut self) -> std::option::OptionAdvance the iterator to the next node (in order) and return a
tuple with a reference to the key and value. If there are no
more nodes, return None.
fn size_hint(&self) -> (uint, std::option::Option)
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).
