Case

class hugr.ops.Case(inputs: list[Type], _outputs: list[Type] | None = None, num_out: int = 0)

Bases: DfParentOp

Parent of a dataflow graph that is a branch of a Conditional.

Methods

inner_signature	Inner signature of the child dataflow graph.
name	Name of the operation.
port_kind	Get the kind of the given port.
used_extensions	Get the extensions used by this operation, optionally resolving unresolved types and operations.

Attributes

num_out
outputs	Outputs of the case operation.
inputs	Inputs types of the inner dataflow graph.

inner_signature() → FunctionType

Inner signature of the child dataflow graph.

inputs: list[Type]

Inputs types of the inner dataflow graph.

name() → str

Name of the operation.

property outputs: list[Type]

Outputs of the case operation.

Raises:

IncompleteOp – If the 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)

used_extensions(resolve_from: ExtensionRegistry | None = None) → ExtensionResolutionResult

Get the extensions used by this operation, optionally resolving unresolved types and operations.

Parameters:

resolve_from – Optional extension registry to resolve against. If None, opaque types and Custom ops will not be resolved.

Returns:

The result containing used and unresolved extensions.
