Opaque¶

class hugr.tys.Opaque(id: str, bound: ~hugr._serialization.tys.TypeBound, args: list[~hugr.tys.TypeArg] = <factory>, extension: str = '')[source]¶

Bases: Type

Opaque type, identified by id and with optional type arguments and bound.

Methods

`resolve`	Resolve the opaque type to an `ExtType` using the given registry.
`to_model`	Convert the type to a model Term.
`type_arg`	The `TypeTypeArg` for this type.
`type_bound`	The bound of this type.

Attributes

`extension`
`id`
`bound`
`args`

resolve(registry: ext.ExtensionRegistry) → Type[source]¶

Resolve the opaque type to an ExtType using the given registry.

If the extension or type is not found, return the original type.

to_model() → Term[source]¶: Convert the type to a model Term.

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.Linear: 'A'>
