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

This API also has ports written for:

• Python3 <http://github.com/ideasman42/rangetree-py>__.
