I was just wondering about the current state of rtree of line segments. That is, what queries does it support? Is the list of predicates on the queries page complete or just a sample? There doesn't seem to be any segment-segment predicates listed, just the nearest query.
I tried to search with index::intersects() to find segments that intersect with another segment and was just surprised to find that it is not implemented.
Is the most efficient way to achieve this behaviour at the moment to query with the bounding box of the segment and then check the results for actual intersection with the segment?
