Struct typedmap::hashmap::TypedKeyValueRef [−][src]
Represents borrowed pair of key and value.
Implementations
impl<'a, Marker> TypedKeyValueRef<'a, Marker>[src]
pub fn downcast_key_ref<K: 'static + TypedMapKey<Marker>>(
&self
) -> Option<&'a K>[src]
&self
) -> Option<&'a K>
Downcast key to reference of K. Returns None if not possible.
pub fn downcast_value_ref<V: 'static + Any>(&self) -> Option<&'a V>[src]
Downcast value and returns reference or None if downcast failed.
pub fn downcast_pair_ref<K: 'static + TypedMapKey<Marker>>(
&self
) -> Option<(&'a K, &'a K::Value)>[src]
&self
) -> Option<(&'a K, &'a K::Value)>
Downcast key to reference of K and value to reference of K::Value.
Returns None if not possible.
