How do I convert a Span to a std::time::Duration?

[chrs-b]

How is it possible to use jiff types with library functions? For instance, tokio::time::sleep.

It would be great to have an impl From<Span> for Duration for instance, so I could use a tokio::time::sleep(1.second().into()).

So my more general question is, how do I convert to and from std::time types?

[BurntSushi]

A impl From<Span> for std::time::Duration is fundamentally impossible.

Have you seen these parts of the docs?

• Integration with std::time::Duration and jiff::SignedDuration
• Span::to_duration
• impl TryFrom<jiff::SignedDuration> for std::time::Duration
• When should I use SignedDuration versus Span?

Thanks so much for pointing out the relevant parts of the documentation (which is great btw) - should have read that first.
I now better understand what a Span is and its difference to SignedDuration.
