MapType

class tierkreis.core.types.MapType(key: TierkreisType, value: TierkreisType)

Bases: TierkreisType

A map from keys of one type to values of another. The key type must be hashable.

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

key
value

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.
