Now I’m trying to decide if you make it better or worse by replacing the == 0 with simple logical negation: if (!(b & ~a)) { … } if (!((WGPUColorWriteMask_Alpha|WGPUColorWriteMask_Blue) & ~mask)) { … } if (!(~a & b)) { … } if (!(~mask & (WGPUColorWriteMask_Alpha|WGPUColorWriteMask_Blue))) { … } Actually, that latter makes a little more intuitive sense to me because of how ! and ~ are both negation¹, so they kinda cancel out and leave just the masking. Kinda. —⁂— ¹ Fun fact: Rust uses ! for both logical and bitwise negation, backed by core::ops::Not, with bool → bool and {integer} → {integer}, since bool is a proper type and there’s no boolean coercion anywhere—so you would have to stick with `== 0` in Rust, though in practice you’d probably go all typey with the bitflags crate’s macro to generate good types with some handy extra methods, and write `mask.contains(WgpuColorWriteMask::Alpha | WgpuColorWriteMask::Blue)`.
