Function Documentation

template<typename T , typename U = size_t>

constexpr U pw::allocator::internal::CountLZero ( T t )

constexpr

Like cpp20:countl_zero, but returns an unsigned type.

Useful for managing the bitmaps that several allocators use to track empty buckets.

template<typename T , typename U = size_t>

constexpr U pw::allocator::internal::CountRZero ( T t )

constexpr

Like cpp20:countr_zero, but returns an unsigned type.

Useful for managing the bitmaps that several allocators use to track empty buckets.
