Struct KeyedSetGuard

Source 
pub struct KeyedSetGuard<'a, K, T, Extractor>
where
    Extractor: for<'z> KeyExtractor<'z, T>,
    for<'z> <Extractor as KeyExtractor<'z, T>>::Key: Hash + PartialEq<K>,
{ /* private fields */ }
Expand description

A guard that allows mutating a value, but which panics if the new value once dropped doesn’t have the same key.
