FuncDecl

class hugr.ops.FuncDecl(f_name: str, signature: tys.PolyFuncType, num_out: int = 1, visibility: Visibility = 'Public')

Bases: Op

Function declaration operation, defines the signature of a function.

Methods

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
visibility	Visibility (for linking).
f_name	function name
signature	polymorphic function signature

f_name: str

function name

name() → str

Name of the operation.

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)

signature: tys.PolyFuncType

polymorphic function signature

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.

visibility: Visibility = 'Public'

Visibility (for linking).
