New API: extraTypeAnnotations

[swankjesse]

The goal of this new API is to allow users to specify extra annotations that'll apply to the Wire-generated classes. This is specifically useful for the @immutable annotation offered by Jetpack Compose, and could be useful for other annotations.

The Compose compiler allows you to provide a list of external types that are stable. So if one provided Wire's Message I think you wouldn't need this feature (Compose will traverse the hierarchy of a type). Unless there are actually other use cases in mind.

Coil did it a few weeks ago coil-kt/coil#1962

Other usecase would be #807

I’m going to shelve this for now because I believe the Compose configuration file can solve my immediate problem.

I think there’s potentially something useful for Wire to do to hint to Compose about what’s immutable.
