Module unsafe_optimizations 

Performance-critical unsafe optimizations

This module contains unsafe code for performance-critical paths in kernel approximation. All unsafe code is carefully reviewed and documented.

Safety

All functions in this module that use unsafe code have detailed safety documentation explaining the invariants that must be upheld.
