Motivation

Simplifies implementations.

Proposal

Warning
This proposal contains API breaking changes.

There are some deprecated APIs in tonic projects. In this proposal, the assumed version is 0.9.2.

deprecated api	deprecated at	alternative api
tonic::service::interceptor_fn	0.5.1	tonic::service::interceptor
tonic::service::interceptor::InterceptorFn	0.5.1	tonic::service::interceptor::InterceptorLayer
tonic::metadata::MetadataValue::try_from_bytes	0.7.2	TryFrom
tonic::metadata::MetadataValue::from_shared	0.7.2	TryFrom
tonic::metadata::MetadataValue::<Ascii>::from_str	0.7.2	TryFrom, FromStr
tonic_build::client::generate	0.8.3	tonic_build::CodeGenBuilder::generate_client
tonic_build::server::generate	0.8.3	tonic_build::CodeGenBuilder::generate_server

The latest deprecation among these APIs is tonic-build 0.8.3 released on November 29, 2022. Also, since there has been corresponding alternative APIs, I think that there has been sufficient period to migrate them.

Alternatives

Maintains these APIs until it becomes necessary to remove them for designs or other reasons.

Yeah, I think it would be good to remove these API's for the next breaking release.

[tottoto]

Thanks for your review. I'll work on this.

I think release wise I may go ahead soon and make a point release since I believe what we have on master now is non-breaking (I checked via cargo-semver-checks but I also need to review the code). Once that is done, we can then do a breaking release with these api changes and some other changes include.
