Yes, you can used the align_packed strategy.

Have you looked at StrPack.jl? It may have a packed option. Julia uses the
platform ABI padding rules for easy interop with C.

For testing/evaluation purposes, it's actually the case that I don't need
to actually use any of the fixed length string fields. They are in the
data, but I have numerical encodings for most of the important ones in
other fields. So in playing around I found that I could just create a
bitstype
Hi Tim,
Thanks for pointing out my basic error. I can now get some test files read
that don't contain any string components.

You'll see why if you type `methods(mmap_array)`: the dims has to be
represented as a tuple.
Currently, the only way I know of to create a fixed-sized buffer as an element
of a "struct" in julia is via immutables with one field per object. Here's one
example:
https://github.com/JuliaGPU/CUDArt.
I'm playing around with Julia for the first time in an attempt to see if I
can replace a Python + Cython component of a system I'm building. Basically
I have a file of bytes representing a numpy structured/recarray (in memory
this is an array of structs). This gets memory mapped into a numpy arr
