431: Add conditional Eq impl for Coordinate, maybe other types? r=frewsxcv a=nick-parker I haven't written tests or anything for this but I wanted to throw the PR in to get discussion started. Many geometry algorithms eg this [optimal algorithm for computing mesh cross-sections and reconstructing the polygons](https://www.researchgate.net/publication/309619647_An_Optimal_Algorithm_for_3D_Triangle_Mesh_Slicing) use Hashtables or similar to keep track of coordinates. This impl lets me put geo Coordinate structs in the Hashtable instead of dealing with a separate struct just for this step. I haven't put much thought into whether similar one-liner Eq impl's should be added for Linestring, Polygon, etc but I don't really see why not. The use cases are rarer but probably still exist. 432: Add Triangle and Rect to Geometry. r=frewsxcv a=frewsxcv Fixes #390 Extracted from https://github.com/georust/geo/pull/421/files Co-authored-by: Nick Parker <[email protected]> Co-authored-by: Corey Farwell <[email protected]>

435: derive Eq for other core geo types r=frewsxcv a=michaelkirk Adds `Eq` conformance to other core geo types, building off of #431 > Seems reasonable to me! Yeah +1 to adding the same impl for all the other core geo types Rather than spelling out the impl, I've taken advantage of how `derive` already bounds the generated impl for us. See rust-lang/rust#21237 for more details I wrote a few doc-tests while developing, but I reverted them in fc33f9f since they're pretty verbose, and seem superfluous since they're only asserting rust language semantics rather than anything substantial in this lib. I can un-revert them if you'd prefer. Co-authored-by: Michael Kirk <[email protected]>
