Interface Map<K, V>

The counterpart of DAML's DA.Map.Map K V type.

This is an immutable map which compares keys via deep equality. The order of iteration is unspecified; the only guarantee is that the order in keys and values match, i.e. m.get(k) is (deep-, value-based) equal to [...m.values()][[...m.keys()].findIndex((l) => _.isEqual(k, l))]

Type parameters

  • K

    The type of the map keys.

  • V

    The type of the map values.
