WebArray support within bitfields to represent repeating bit patterns. Basic declaration A bit field is created similar to a regular Rust struct. Annotations define the layout of the structure. As an example, consider the following definition, which specifies a bit field: Web#[bitfield(u32)] specifies that this is a bitfield in which u32 is the underlying data type. This means that all the bits inside of the bitfield have to fit within 32 bits. u8, u16, u32, u64 …
