Function DecodeGeoDescending

pkg/util/encoding/encoding.go:1412–1433

DecodeGeoDescending decodes a geopb.SpatialObject value that was encoded in descending order back into a geopb.SpatialObject. The so parameter must already be empty/reset.

(b []byte, so *geopb.SpatialObject)

// must already be empty/reset.
