Concept definition

template<typename E>
concept terra::util::FlagLike =  std::is_enum_v< E > && std::unsigned_integral< std::underlying_type_t< E > > &&
                   ( static_cast< std::underlying_type_t< E > >( E::NO_FLAG ) == 0 )

Detailed Description

Concept for types that behave like bitmask flags.

This concept checks if a type E is an enum with an unsigned integral underlying type, has a NO_FLAG value equal to 0, and supports bitwise OR (|) and AND (&) operations.
