PolyFuncType

class hugr.tys.PolyFuncType(params: list[TypeParam], body: FunctionType)

Bases: Type

Polymorphic function type or type scheme. Defined by a list of type parameters that may appear in the FunctionType body.

Methods

empty	Generate an empty polymorphic function type.
resolve	Resolve types in the polymorphic function type using the given registry.
type_arg	The TypeTypeArg for this type.
type_bound	The bound of this type.
with_runtime_reqs	Adds a list of extension requirements to the function type, and returns the new signature.

Attributes

params
body

classmethod empty() → PolyFuncType

Generate an empty polymorphic function type.

Example

>>> PolyFuncType.empty()
PolyFuncType(params=[], body=FunctionType([], []))

resolve(registry: ext.ExtensionRegistry) → PolyFuncType

Resolve types in the polymorphic function type using the given registry.

type_arg() → TypeTypeArg

The TypeTypeArg for this type.

Example

>>> Qubit.type_arg()
TypeTypeArg(ty=Qubit)

type_bound() → TypeBound

The bound of this type.

Example

>>> Tuple(Bool, Bool).type_bound()
<TypeBound.Copyable: 'C'>
>>> Tuple(Qubit, Bool).type_bound()
<TypeBound.Any: 'A'>

with_runtime_reqs(runtime_reqs: list[str]) → PolyFuncType

Adds a list of extension requirements to the function type, and returns the new signature.
