Summary
Add
merge2toMessagewhich is a wrapper toprost::Message::merge. Added as an undocumented (hidden) method on Message that is primarily an implementation detail internal to busan.Motivation
The
Message::mergefunction from prost requires that self beSized.merge2allows us to call the merge function through dynamic dispatch by implementingmerge2on the object and not in the trait.Test Plan
It compiles. Usages will come later for further testing/refinement.
