Range Tree
Data type for storing non-overlapping scalar ranges. The underlying representation is a red-black tree for fast manipulation.
Usage
This may be used for tracking free ID's or ranges.
Ranges are typically integers however generic types are used,
so any type with a One
and Zero
trait (along with addition and subtraction support)
may be used.

Further Work
While the API is complete on a basic level, there are some additions that could be useful.
- Range Queries: to check if a value within a range is taken.
- Boolean Operations: support for performing binary operations on range-trees (and, or, xor, invert).
- Set Operations: is-subset, is-superset, is-disjoint.
- Interval Iterator: to loop over used or unused intervals.
Ports
