The message 1 is invalid: * The first word of the subject ("Upgrade") must not match the first word of the body. Please make the body more informative by adding more information instead of repeating the subject. For example, start by explaining the problem that this change is intended to solve or what was previously missing (e.g., "Previously, ...."). The original message was: Upgrade `tonic` and `prost` Upgrade `tonic` to version 0.12, as a prerequisite to later on upgrading `hyper`. As of version 1, `hyper` no longer uses tokios `AsyncWriter` and `AsyncReader` traits, instead defining its own versions, see <https://github.com/hyperium/hyper/issues/3110>. As tonic `0.12` is updated to use the `hyper 1.0` ecosystem, it changed some of its trait-bounds to the new `hyper` traits. The `hyper-utils` crate provides the wrapper `TokioIo`, which converts between the two. `prost` had to be upgraded as well, for compatibility.
