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

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.

Attributes

`params`
`body`

classmethod empty() → PolyFuncType[source]#

Generate an empty polymorphic function type.

Example

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

resolve(registry: ext.ExtensionRegistry) → PolyFuncType[source]#: 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[source]#

The bound of this type.

Example

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