def raise_invalid_type(value : _, supported_types : String) : NoReturn #

Can be used to raise an AVD::Exceptions::UnexpectedValueError in case self is only able to validate values of the supported_types.

# Define a validate method to catch values of other types.
# Overloads above would handle the valid types.
def validate(value : UNDERSCORE, constraint : AVD::Constraints::MyConstraint) : Nil
  self.raise_invalid_type value, "Int | Float"
end

This would result in a violation with the message This value should be a valid: Int | Float being added to the current #context.

def validate(value : _, constraint : AVD::Constraint) : Nil #
