Struct hashbrown::hash_map::DrainFilter[][src]

pub struct DrainFilter<'a, K, V, F> where
    F: FnMut(&K, &mut V) -> bool, 
{ /* fields omitted */ }

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

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