Output

class hugr.ops.Output(_types: list[Type] | None = None, num_out: int = 0)[source]

Bases: DataflowOp, _PartialOp

Output operation in dataflow graph. Inputs of this operation are the outputs of the graph.

Methods

name

Name of the 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.

Attributes

num_out

types

name() str[source]

Name of the operation.

outer_signature() FunctionType[source]

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

Raises:

IncompleteOp – If the operation’s inputs and outputs have not been set.

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
