This looks like a nice simple alternative. I haven't touched StrPack in a long time, but I believe the analogous StrPack syntax is: @struct type MyStruct field1::UInt8 field2::Byte end, align_packed Though since these are both 1-byte fields, there wouldn't be any padding under the default strategy anyways. I'm not sure if this works with immutables--someone may have contributed that? Maintainer neglect of StrPack is acknowledged :D Have you considered possibly spinning your simplified version into its own package, Tom? StrPack is/was pretty ambitious; I wanted to be able to get down to bit-level unpacking, with the goal of being able to parse a Novatel RANGECMP log (http://www.novatel.com/assets/Documents/Bulletins/apn031.pdf) entirely with an annotated type declaration. I'd still like to do this, but it's been hard to find the motivation to work on it. (There's a branch up on the repository which pushes towards this, but the work is incomplete.) The manual alternative Stefan proposes is definitely a good option, especially if this is a one-off structure.
