pub struct TrieSetIterator<'self> {
priv iter: TrieMapIterator<'self, ()>,
}Forward iterator over a set
impl<'self> Iterator<uint> for TrieSetIterator<'self>fn next(&mut self) -> Option<uint>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.
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).
