Detailed Description

Internal constraint for native unsigned integer types.

This concept matches exactly the unsigned integer types that can directly back a bitflags<N> specialization: uint8_t, uint16_t, uint32_t, and uint64_t.

It exists solely to enable optimized implementations where the entire bitset can be represented and manipulated as a single native integer, allowing constant-time bitwise operations and efficient popcount.

Internal use only. This concept is not part of the public API and must not be relied upon by user code.
