What we need to do IO in Julia with guaranteed memory safety

If you know that the alignment of your data is correct (maybe you have written the data from Julia) you could just use Mmap.mmap(“filename”, Vector{MyType}) instead of going through a Vector{UInt8} and then using reinterpret on that.

It’s a little more complicated than that because it’s not just a single Vector{MyType}, it’s lots of vectors containing lots of different types aranged in a non-trivial format, as well as a bunch of FlatBuffer structs.
