DataflowOp#

class hugr.ops.DataflowOp(*args, **kwargs)[source]#

Abstract dataflow operation. Can be assumed to have a signature and Value- kind ports.

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

The number of output ports for this operation.

property num_out: int#

The number of output ports for this operation.

Example

>>> op = Const(val.TRUE)
>>> op.num_out
1

outer_signature() → FunctionType[source]#: The external signature of this operation. Defines the valid external connectivity of the node the operation belongs to.

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[source]#

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
