Struct hashbrown::hash_set::DrainFilter[][src]

pub struct DrainFilter<'a, K, F, A: Allocator + Clone = Global> where
    F: FnMut(&K) -> bool
{ /* fields omitted */ }

A draining iterator over entries of a HashSet which don’t satisfy the predicate f.

This struct is created by the drain_filter method on HashSet. See its documentation for more.
