TierkreisValue

class tierkreis.core.values.TierkreisValue

Bases: ABC

Abstract base class for all Tierkreis compatible values.

Methods

from_proto	Parses a tierkreis type from its protobuf representation.
from_python	Converts a python value to a tierkreis value.
from_python_union	Converts a python value to a tierkreis value, given a target python Union type.
to_proto
to_python	Converts a tierkreis value to a python value given the desired python type.
to_python_union	Converts a tierkreis value to a python value given the desired union type.
try_autopython	Try to automatically convert to a python type without specifying the target types.
viz_str	String representation used in graph visualisation.

classmethod from_proto(value: Any) → TierkreisValue

Parses a tierkreis type from its protobuf representation.

classmethod from_python(value: Any, type_: Type | None = None) → TierkreisValue

Converts a python value to a tierkreis value. If type_ is not provided, it is inferred from the value.

classmethod from_python_union(value: Any, type_: UnionType) → TierkreisValue

Converts a python value to a tierkreis value, given a target python Union type.

to_python(type_: Type[T]) → T

Converts a tierkreis value to a python value given the desired python type.

When the specified python type is a type variable, the original TierkreisValue is returned unchanged. This allows us to write generic functions in which values of unknown type are passed on as they are.

to_python_union(type_: UnionType) → Any

Converts a tierkreis value to a python value given the desired union type.

try_autopython() → Any | None

Try to automatically convert to a python type without specifying the target types. Returns None if unsuccessful. Expected to be successful for “simple” or “leaf” types, that are not made up component types.

return:

Python value if successful, None if not.

rtype:

Optional[Any]

abstract viz_str() → str

String representation used in graph visualisation.
