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.
I have made some minor changes to make adaptors responsible for
allocating buffers. This made it possible to add a new adaptor
MemoryMapped and a sample to show it off.
I have also verified that no buffer allocations happen while
reading using MemoryMapped.
Note that writing using memory mapping is still not possible.
