Enum SDuration

pub(crate) enum SDuration {
    Span(Span),
    Absolute(SignedDuration),
}

An internal type for abstracting over signed durations.

This is typically converted to from a Duration. It enables callers downstream to implement datetime arithmetic on only two duration types instead of doing it for three duration types (including std::time::Duration).

The main thing making this idea work is that if an unsigned duration cannot fit into a signed duration, then it would overflow any calculation on any datetime type in Jiff anyway. If this weren’t true, then we’d need to support doing actual arithmetic with unsigned durations separately from signed durations.

Variants

Span(Span)

Absolute(SignedDuration)
