Trait ExecSpecSetDifference 

Source 
pub trait ExecSpecSetDifference<'a, Out: Sized + DeepView>:
    Sized
    + DeepView
    + ToOwned<Out> {
    // Required method
    exec fn exec_difference(self, s2: Self) -> Out;
}

Implementations on Foreign Types§

Source§

impl<'a, K> ExecSpecSetDifference<'a, HashSet<K>> for &'a HashSet<K>
where K: DeepView + DeepViewClone + Hash + Eq,

Source§

exec fn exec_difference(self, s2: Self) -> res : HashSet<K>

ensures
res.deep_view() =~= self.deep_view().difference(s2.deep_view()),
