This is incredible news! I’ve used protobuf in Python, Go, Kotlin and Dart and the Python implementation is totally unusable. I don’t know what black magic Google uses for the Python implementation, but the classes it generates are totally opaque and impossible to inspect. I’ve been waiting for a proper python implementation for years now!

TFA seems to say that they’re just thin proxies over the underlying C++ APIs, which would more than do it, and does not surprise me (the re2 Python bindings are similar, not as bad since they don’t generate Python code but they’re really c++-y — in Google’s flavour too — and uncomfortable).
rust code tends to be incredibly slow unless you spend a ton of time optimizing (compared to other compiled languages, and contrary to popular belief).
When I was a novice in protobuf I felt tempted to inspect the generated code, but soon I learned that the documentation is good enough that I don’t need to read the generated code.
