I changed the title of this issue to emphasize that we're talking about IXDTF, which is not functionality I'm aware of in Rust except for temporal_rs mentioned above.

Thanks for the reference! Looking over that code, it seems to be well-written and suitable as a dependency of the icu4x project. I think it would be worthwhile pulling this...

Discussion: after @nekevss's PR is landed, we will add `ixdtf` as an optional, default dependency of `icu_calendar` and use where necessary. LGTM: @sffc @Manishearth @robertbastian

#4646 basically fixes this issue but there were some minor follow-ups. I'm re-opening this issue to track that, or we can move those to another issue and re-close this one.

@FrankYFTang is working on this in ICU4C. We should coordinate with him at that time. We can do this in a non-breaking way.

I think this is done, because CompactDecimal and ScientificDecimal are landed.

Segmenter has been moved to components and is being released in 1.2. Closing this tracking issue.

- @sffc - Is this a property we want to retain in the style guide? - @Manishearth - I think it's helpful when things have debug impls, but the debug...

Note that we will want to support both directions. In ICU these are `Calendar::setTime` and `Calendar::getTime`.
