@galargh any idea why I can't add a reviewer to this PR? I looked at github-mgmt but couldn't figure out what in there would allow me to do that. |

@DougAnderson444 could you give this a review for me? |

@galargh nvrmnd, it auto-added the rust-libp2p maintainers |

It seems this functions don't need to be copy pasted, you can use quick-protobuf-codec see libp2p/rust-libp2p#4788 (comment)

ah thanks! I'll fix it.

So I took a look at the quick-protobuf-codec example and it assumes that the messages are protobuf generated structs with a specific interface. I think leaving the manual varuint-length-prefixed-messages code in here is better. It amounts to a re-implementation of the quick-protobuf-codec without the protobufs.
In the future we may want to add to the misc/ folder an implementation of a "length-prefixed-codec" that has a public Trait HasLength (or whatever) that defines a single fn get_length() -> usize function. Then the codec can have generic parameters that have the trait bounds of HasLength + AsRef<[u8]>.
Now that I think about it, it should probably use something like a SHA3 sponge construction where the protocol and the message type are mixed in as associated data and then the length is mixed and then then length is written followed by a MAC then the data is mixed in and written followed by another MAC to give the messages some authentication data.
Anyway, I think we should leave this as-is and just land it.
Thanks for the review.
