Examples

Core

The core of orderings is the Ordering enumeration and the Compare protocol:

from attrs import frozen
from orderings import Compare, Ordering

I = TypeVar("I", bound="Int")


@frozen()
class Int(Compare):
    value: int

    def compare(self: I, other: I) -> Ordering:
        self_value = self.value
        other_value = other.value

        if self_value < other_value:
            return Ordering.LESS

        if self_value > other_value:
            return Ordering.GREATER

        return Ordering.EQUAL

Compare implements all ordering operations (==, !=, <, >, <=, >=) using the compare method.
