Written by Claude and friends \u2763\ufe0f\n\n## Why buffa?\n\nThe Rust ecosystem lacks an actively maintained, pure-Rust library that supports [protobuf editions](https://protobuf.dev/editions/overview/). Buffa fills that gap with a ground-up design that treats editions as the core abstraction. It passes the full protobuf conformance suite \u2014 binary, JSON, and text \u2014 with zero expected failures.\n\n## Features\n\n- **Editions-first.** Proto2 and proto3 are understood as feature presets within the editions model. One code path, parameterized by resolved features.\n\n- **Two-tier owned/borrowed types.** Each message generates both `MyMessage` (owned, heap-allocated) and `MyMessageView\u003c\u0027a\u003e` (zero-copy from the wire). `OwnedView\u003cV\u003e` wraps a view with its backing `Bytes` buffer for use across async boundaries.\n\n- **`MessageField\u003cT\u003e`.** Optional message fields deref to a default instance when unset -- no `Option\u003cBox\u003cT\u003e\u003e` unwrapping ceremony.\n\n- **`EnumValue\u003cT\u003e`.** Type-safe open enums with proper Rust `enum` types and preservation of unknown values, instead of raw `i32`.\n\n- **Linear-time serialization.** Cached encoded sizes prevent the exponential blowup that affects libraries without a size-caching pass.\n\n- **Un",
