ExecSpecMapIndex

Trait ExecSpecMapIndex 

Source
pub trait ExecSpecMapIndex<'a>: Sized + DeepView<V = Map<<Self::Key as DeepView>::V, <Self::Value as DeepView>::V>> {
    type Key: DeepView;
    type Value: DeepView;

    // Required method
    exec fn exec_index(self, key: Self::Key) -> Self::Value;
}
Expand description

Spec for executable version of Map indexing.

Required Associated Types§

Required Methods§

Source

exec fn exec_index(self, key: Self::Key) -> Self::Value

requires
self.deep_view().dom().contains(key.deep_view()),

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types§

Source§

impl<'a, K: DeepView + Hash + Eq, V: DeepView> ExecSpecMapIndex<'a> for &'a HashMap<K, V>

Source§

exec fn exec_index(self, index: Self::Key) -> res : Self::Value

ensures
res.deep_view() == self.deep_view()[index.deep_view()],
Source§

type Key = K

Source§

type Value = &'a V
