This isn't going to work for requests sent in multi's, ie. all mutate requests, since a multi's Context() method just returns context.Background().

Maybe you don't care about that case. Just wanted to raise it in case you weren't aware. If you did want it to work for multi's you'd probably have to find the latest Deadline among the requests and use that as your timeout.

if ok {
// Timeout shouldn't be negative, as we just tested the .Done() channel before entering this
// function. But if this happen, it's okay, the cast to uint32 will give us a big timeout
// value.
timeout := time.Until(deadline)
header.Timeout = proto.Uint32(uint32(timeout.Milliseconds()))
}

if s, ok := rpc.(canSerializeCellBlocks); ok && s.CellBlocksEnabled() {
// request can be serialized to cellblocks
request, cellblocks, cellblocksLen = s.SerializeCellBlocks()
