Struct SplitPoint 

pub struct SplitPoint { /* private fields */ }

A boundary between adjacent range partitions.

A split point is a tuple with one ScalarValue per partitioning expression. Split points are interpreted lexicographically according to the ordering of the range partitioning that owns them.

N split points define N + 1 partitions:

partition 0: key < split_points[0]
partition 1: split_points[0] <= key < split_points[1]
...
partition N - 1: split_points[N - 2] <= key < split_points[N - 1]
partition N: split_points[N - 1] <= key

Values equal to split point i belong to partition i + 1, so interior partitions are lower-inclusive and upper-exclusive.

Implementations
