Swift and C structures in memory

Load/save simple struct in chunks

I have a simple struct (nested struct of primitive types/enum) and want to load from/save to large file in chunks, sometimes in time-critical region. Right now I'm exploring my options. I could use Codable, but JSON doesn't seem to support random access (you have to parse the entire file). I don't want to load the entire file into memory. I could separate each chunk and encode/decode them independently, but then I don't know the upper limit of the encoded data size. I could implement Binar…

Also similar topic about the layout of data. Essentially there’s little one can say about the memory layout.
