What is libcritnib-dev
libcritnib-dev is:
Critnib is a data structure that provides a very fast equal and less-than/greater-than searches; it is a mix between DJBerstein’s critbit and radix trees. While in bad cases it has worse memory use than binary trees, it works well on real-life data which tends to have a limited number of “decision bits”:
- fully random: divergence happens immediately
- malloc addresses: clumps of distinct bits in the middle
- sequences: only lowest bits are filled
This library ships only uintptr_t→uintptr_t mappings, optimized for reads from a very critical section but not so frequent writes. Other variants also exist (such as fully lock-free writes, keys of arbitrary length), and can be added upon request.
