class cirq.Unique(val: T)[source]

A wrapper for a value that doesn’t compare equal to other instances.

For example: 5 == 5 but Unique(5) != Unique(5).

Unique is used by CircuitDag to wrap operations because nodes in a graph
are considered the same node if they compare equal to each other. X(q0)
in one moment of a Circuit and X(q0) in another moment of the Circuit are
wrapped by Unique(X(q0)) so they are distinct nodes in the graph.
