Input

class hugr.ops.Input(types: list[Type])

Bases: DataflowOp

Input operation in dataflow graph. Outputs of this operation are the inputs to 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	The number of output ports for this operation.
types

name() → str

Name of the 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

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
