Function EncodeGeoDescending

pkg/util/encoding/encoding.go:1370–1382

EncodeGeoDescending encodes a geopb.SpatialObject value in descending order and returns the new buffer. It is sorted by the given curve index, followed by the bytes of the spatial object.

// returns the new buffer.
// It is sorted by the given curve index, followed by the bytes of the spatial object.
