Ok, thanks. I took a look at several capnproto implementations
just now, and didn't see any tests for a mmap 'feature'. The
roadmap doc below indicates it doesn't exist, and perhaps there
are some details yet to be resolved to make it 'friendly' for a
mmap.
But reading using random access *is* a feature of Cap'n Proto. So
when reading a memory mapped Cap'n Proto file, getters will be
faster if you use it in a non-sequential way.
The format of Cap'n Proto doesn't currently support *writing* to
a memory mapped file.
