cirq_google.serialization.op_serializer.OpSerializer

Generic supertype for operation serializers.

Each operation serializer describes how to serialize a specific type of Cirq operation to its corresponding proto format. Multiple operation types may serialize to the same format.

Attributes
`can_serialize_predicate`	The method used to determine if this can serialize an operation. Depending on the serializer, additional checks may be required.
`internal_type`	Returns the type that the operation contains. For GateOperations, this is the gate type. For CircuitOperations, this is FrozenCircuit.
`serialized_id`	Returns the string identifier for the resulting serialized object. This ID denotes the serialization format this serializer produces. For example, one of the common serializers assigns the id 'xy' to XPowGates, as they serialize into a format also used by YPowGates.

Attributes

can_serialize_predicate

The method used to determine if this can serialize an operation.

Depending on the serializer, additional checks may be required.

internal_type

Returns the type that the operation contains.

For GateOperations, this is the gate type. For CircuitOperations, this is FrozenCircuit.

serialized_id

Returns the string identifier for the resulting serialized object.

This ID denotes the serialization format this serializer produces. For example, one of the common serializers assigns the id 'xy' to XPowGates, as they serialize into a format also used by YPowGates.

Methods

`can_serialize_operation`

View source

can_serialize_operation(
    op: cirq.Operation
) -> bool

Whether the given operation can be serialized by this serializer.

`to_proto`

View source

@abc.abstractmethod
to_proto(
    op,
    msg=None,
    *,
    arg_function_language: Optional[str] = '',
    constants: List[cirq_google.api.v2.program_pb2.Constant],
    raw_constants: Dict[Any, int]
) -> Optional[cirq_google.api.v2.program_pb2.CircuitOperation]

Converts op to proto using this serializer.

If self.can_serialize_operation(op) == false, this should return None.

Args
`op`	The Cirq operation to be serialized.
`msg`	An optional proto object to populate with the serialization results.
`arg_function_language`	The `arg_function_language` field from `Program.Language`.
`constants`	The list of previously-serialized Constant protos.
`raw_constants`	A map raw objects to their respective indices in `constants`.

Returns
The proto-serialized version of `op`. If `msg` was provided, it is the returned object.
