MakeTuple

class hugr.ops.MakeTuple(_types: list[Type] | None = None, num_out: int = 1)

Bases: AsExtOp, _PartialOp

Operation to create a tuple from a sequence of wires.

Methods

cached_signature	Cached signature of the operation, if there is one.
from_ext	Load from a ExtOp operation.
name	Name of the operation.
op_def	The tys.OpDef for this operation.
outer_signature	The external signature of this operation.
port_kind	Get the kind of the given port.
port_type	Get the type of the given dataflow port from the signature of the operation.
type_args	Type arguments of the operation.

Attributes

ext_op	ExtOp operation that this type represents.
num_out
types	If set, the types of the tuple elements.

exception InvalidExtOp(msg: str)

Bases: Exception

Extension operation does not match the expected type.

with_traceback()

Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.

cached_signature() → FunctionType | None

Cached signature of the operation, if there is one.

Used by op_def, so must be deterministic.

property ext_op: ExtOp

ExtOp operation that this type represents.

Computed once using op_def() type_args() and type_args(). Each of those methods should be deterministic.

classmethod from_ext(ext_op: ExtOp) → Self | None

Load from a ExtOp operation.

By default assumes the type of cls is a singleton, and compares the result of to_ext() with the given ext_op.

If successful, returns the singleton, else None.

Non-singleton types should override this method.

Raises:

• InvalidCustomOp – If the given ext_op does not match the expected one for a

• given extension/operation name. –

name() → str

Name of the operation.

op_def() → ext.OpDef

The tys.OpDef for this operation.

Used by ext_op, so must be deterministic.

outer_signature() → FunctionType

The external signature of this operation. Defines the valid external connectivity of the node the operation belongs to.

port_kind(port: InPort | OutPort) → ValueKind | ConstKind | FunctionKind | CFKind | OrderKind

Get the kind of the given port.

Example

>>> op = Const(val.TRUE)
>>> op.port_kind(OutPort(Node(0), 0))
ConstKind(Bool)

port_type(port: InPort | OutPort) → Type

Get the type of the given dataflow port from the signature of the operation.

Example

>>> op = Input([tys.Bool])
>>> op.port_type(OutPort(Node(0), 0))
Bool

type_args() → list[TypeArg]

Type arguments of the operation.

Used by op_def, so must be deterministic.

property types: list[Type]

If set, the types of the tuple elements.

Raises:

IncompleteOp – If the types have not been set.
