friend constexpr mask_type operator==(const basic_vec& lhs, const basic_vec& rhs) noexcept; friend constexpr mask_type operator!=(const basic_vec& lhs, const basic_vec& rhs) noexcept; friend constexpr mask_type operator>=(const basic_vec& lhs, const basic_vec& rhs) noexcept; friend constexpr mask_type operator<=(const basic_vec& lhs, const basic_vec& rhs) noexcept; friend constexpr mask_type operator>(const basic_vec& lhs, const basic_vec& rhs) noexcept; friend constexpr mask_type operator<(const basic_vec& lhs, const basic_vec& rhs) noexcept;
Let op be the operator.
Constraints: requires (value_type a, value_type b) { a op b; } is true.
Returns: A basic_mask object initialized with the results of applying op to lhs and rhs as a binary element-wise operation.
