Derive Macro BitPacked 

#[derive(BitPacked)]
{
    // Attributes available to this derive:
    #[bits]
}

Available on crate features bit-packing and derive only.

Derives rustbinary::BitPack for structs and enums.

Fields with #[bits = N] use BitValue range validation. Other fields recursively use BitPack. Enum tags use the minimum bit width and unknown decoded tags are rejected.
