There was a problem hiding this comment.
I thought it was worth future-proofing, so we don't have to bump WKT's minimum version of geo-types again if we add to the error enum.

This is a really big ergonomic improvement; the enum is really useful, but it's been historically awkward to work with and this removes a lot of that friction 👍👍👍 |

614: Specify the details of conversion failures in an exported error enum r=michaelkirk a=michaelkirk - [x] I agree to follow the project's [code of conduct](https://github.com/georust/geo/blob/master/CODE_OF_CONDUCT.md). - [x] I added an entry to `CHANGES.md` if knowledge of this change could be valuable to users. --- I came across this while trying to improve ergonomics of the WKT crate, which relies on this conversion logic. (see georust/wkt#57) I *think* this is not a breaking change (see comment inline), but would appreciate confirmation. If I'm wrong, and it indeed is a breaking change, I'd prefer to hold off on merging it for now. Co-authored-by: Michael Kirk <michael.code@endoftheworl.de>
