Honestly, the Contains functionality is outside the bounds of what this library is attempting to do, which is be an API client library.

I'd suggest looking http://tile38.com/ for a MIT licensed in-memory geolocation data store, spatial index, and realtime geofence service written in Go. =)

Sure! I'll try.

Do you have any reference implementation or mathematical theory to afford this problem?

I think the answer over here: https://s2geometry.io/about/overview and https://godoc.org/github.com/golang/geo/s2

Continue researching...

Just for contributing with someone else, this is how I resolved this:

func extendBounds(bounds1, bounds2 maps.LatLngBounds) maps.LatLngBounds {

	boundsPoints := []s2.Point{}
	point1 := s2.PointFromLatLng(s2.LatLngFromDegrees(bounds1.NorthEast.Lng, bounds1.NorthEast.Lat).Normalized())
	point2 := s2.PointFromLatLng(s2.LatLngFromDegrees(bounds1.SouthWest.Lng, bounds1.NorthEast.Lat).Normalized())
	point3 := s2.PointFromLatLng(s2.LatLngFromDegrees(bounds1.SouthWest.Lng, bounds1.SouthWest.Lat).Normalized())
	point4 := s2.PointFromLatLng(s2.LatLngFromDegrees(bounds1.NorthEast.Lng, bounds1.SouthWest.Lat).Normalized())
	boundsPoints = append(boundsPoints, point1, point2, point3, point4)
	point1 = s2.PointFromLatLng(s2.LatLngFromDegrees(bounds2.NorthEast.Lng, bounds2.NorthEast.Lat).Normalized())
	point2 = s2.PointFromLatLng(s2.LatLngFromDegrees(bounds2.SouthWest.Lng, bounds2.NorthEast.Lat).Normalized())
	point3 = s2.PointFromLatLng(s2.LatLngFromDegrees(bounds2.SouthWest.Lng, bounds2.SouthWest.Lat).Normalized())
	point4 = s2.PointFromLatLng(s2.LatLngFromDegrees(bounds2.NorthEast.Lng, bounds2.SouthWest.Lat).Normalized())
	boundsPoints = append(boundsPoints, point1, point2, point3, point4)
	loop := s2.LoopFromPoints(boundsPoints)
	loop.Normalize()

	rect := loop.RectBound()
	hi := rect.Hi()
	lo := rect.Lo()

	return maps.LatLngBounds{NorthEast: maps.LatLng{Lat: hi.Lat.Degrees(), Lng: hi.Lng.Degrees()}, SouthWest: maps.LatLng{Lat: lo.Lat.Degrees(), Lng: lo.Lng.Degrees()}}
}
