Eh, I like having the APIs be in words in hopes that it reminds people to think about alignment. When allocating space for a capnp message, you should always allocate an array of words, not an array of bytes.
Seems not too hard for the caller to multiply by sizeof(capnp::word) if needed? -Kenton On Wed, May 6, 2020 at 4:49 PM Vitali Lovich <vlov...@gmail.com> wrote: > The optometrist tells me I have 20/20 vision but I think it must clearly > be a lie at this point :).
