How to go from a GeoJSON Feature to a set of geohashes?

[lorenzofelletti]

First of all, I hope that I am posting in the right place (I apologize if I am not).

I have a GeoJSON file that contains a polygon for each districts of a city. What I would like to get is, for each district, the set of geohashes that are contained within the district's polygon. To decode the GeoJSON I'm using the geojson crate, for the geohashes the geohash create, but I did not found in the documentation a way to do something like:

• from a geojson::geometry::Geometry

geometry.geohashes_inside(precision)

Does someone has already faced something similar, and can point me out some resources to be able to find a solution for my problem?

I don't think this belongs to geo, but neither does it belong to geohash as far as I can see.

I believe the best option is to define a grid of the resolution you want, pick the squares that intersect your geometry, then encode their centres using geohash.

Sorry for mis-posting and the late response.
First, thank you for your suggestion!
Second, in case this could be helpful to someone in the future, I found something implementing just the functionality I needed here.
