Conversion from Bytes to Vec<u8>?

[akiradeveloper]

According to this thread 824a986 conversion from Bytes to Vec<u8> has ever existed but not found today. Is it deleted? but what reason? Is there some workaround today?

I want to use Bytes entirely in my library. It is a Raft library using gRPC. To send RPC I need to make Vec<u8> as payload (I hope prost generates code using Bytes instead of Vec<u8> though), if there is no cost to extract Vec<u8> from Bytes when refcnt=1 that would push me forward to fully depend on Bytes.

I think you should look into just using Bytes everywhere.

Bytes in the end is a type-erased buffer, and it may or may not contain a Vec<u8>. Depending on what it is - which might again depend on the current version of Bytes - the conversion might either be rather cheap or involve a full allocation and copy.

Prost now supports this, and it’s compatible with Tonic 0.4.0, which was
released today. Have fun!

I work with two libraries each exposing a different version of bytes. Having a non-allocating conversion Into<Vec<u8>> would allow me convert between both versions.

I'd love to have this as well; I've had to write an equivalent conversion several times, and I'd love to have a canonical implementation in bytes itself.
