PairType

class tierkreis.core.types.PairType(first: TierkreisType, second: TierkreisType)

Bases: TierkreisType

A pair of two types.

Methods

children	For composite types (e.g. Struct, Vec, Map), list the child types that define it concretely.
contained_vartypes
from_proto	Attempts to convert a protobuf type to a TierkreisType subclass.
from_python	Create a TierkreisType from a corresponding Python type.
from_python_union	Create a TierkreisType from a Union type.
register_alternative	Register an alternative type that can be used to convert to/from TierkreisType.
to_proto	Converts a tierkreis type to its protobuf representation.

Attributes

first
second

children() → list[TierkreisType]

For composite types (e.g. Struct, Vec, Map), list the child types that define it concretely.

classmethod from_proto(type_: Type) → TierkreisType

Attempts to convert a protobuf type to a TierkreisType subclass.

classmethod from_python(type_: Type, visited_types: dict[Type, TierkreisType] | None = None) → TierkreisType

Create a TierkreisType from a corresponding Python type.

Parameters:

• type – The Python type.

• visited_types – An optional map from previously visited Python types

• TierkreisType (to)

• recursively. (used when converting)

Raises:

• IncompatibleUnionType – Failure to convert a Union.

• IncompatiblePyType – Python type cannot be converted to a Tierkreis type.

Returns:

TierkreisType

classmethod from_python_union(type_: UnionType, visited_types: dict[Type, TierkreisType] | None = None) → TierkreisType

Create a TierkreisType from a Union type.

classmethod register_alternative(type_: Type, alternative: Type[SerializeAs])

Register an alternative type that can be used to convert to/from TierkreisType.

to_proto() → Type

Converts a tierkreis type to its protobuf representation.
