Trait kas::view::DataKey

pub trait DataKey: Clone + Debug + Default + PartialEq + Eq + 'static {

Bounds on the key type

Required Methods

fn make_id(&self, parent: &Id) -> Id

Make an Id for a key

The result must be distinct from parent. Use Id::make_child.

fn reconstruct_key(parent: &Id, child: &Id) -> Option<Self>

Reconstruct a key from an Id

Where child is the output of Self::make_id for the same parent or any Id descended from that, this should return a copy of the key passed to make_id.

See: Id::next_key_after, Id::iter_keys_after

Object Safety

This trait is not object safe.
