class Expression:

Root base class for all model-checker expressions. Provides pythonic magic-method sugar for expression definitions.

def one_of(self, *values):
@classmethod
def from_py(cls, value):

Creates an :py:Expression: from a given python value.

def top_json(self) -> Dict[str, object]:

Creates a top-level expression that can be passed to the model checker runtime.

class Variable(Expression):

Declares a model variable that can be used as an :py:Expression: in the model checker. Variables are identified by their model_name, a position of either "input" or "output", and the tensor index.

def instrument( values: Dict[str, wallaroo.checks.Expression], gauges: List[str], validations: List[str]):
def dns_compliant(name: str):

Returns true if a string is compliant with DNS label name requirement to ensure it can be a part of a full DNS host name

def require_dns_compliance(name: str):

Validates that 'name' complies with DNS naming requirements or raises an exception
