A trait composition for types which implement all requirements of dictionary keys. Dict keys must minimally be Movable, Hashable, and EqualityComparable for a hash map. Until we have references they must also be copyable.

Methods
__copyinit__
__copyinit__(out self: _Self, existing: _Self, /)
Create a new instance of the value by copying an existing one.
Args:
- existing (
_Self): The value to copy.
__moveinit__
__moveinit__(out self: _Self, owned existing: _Self, /)
Create a new instance of the value by moving the value of another.
Args:
- existing (
_Self): The value to move.
__eq__
__eq__(self: _Self, other: _Self) -> Bool
Define whether two instances of the object are equal to each other.
Args:
- other (
_Self): Another instance of the same type.
Returns:
True if the instances are equal according to the type's definition of equality, False otherwise.
__ne__
__ne__(self: _Self, other: _Self) -> Bool
Define whether two instances of the object are not equal to each other.
Args:
- other (
_Self): Another instance of the same type.
Returns:
True if the instances are not equal according to the type's definition of equality, False otherwise.
__hash__
__hash__(self: _Self) -> UInt
Return a 64-bit hash of the type's data.
Returns:
A 64-bit integer hash of this instance's data.
