Overview ¶
Package protosource defines minimal interfaces for Protobuf descriptor types.
This is done so that the backing package can be swapped out easily.
All values that return SourceLocation can be nil.
Testing is currently implicitly done through the bufcheck packages, however if this were to be split out into a separate library, it would need a separate testing suite.
