About:
Protozero is a lightweight, zero-dependency C++ library for reading and writing protocol buffer messages. It operates directly on serialized byte streams without requiring generated code or a runtime library. This approach provides high performance and minimal overhead, making it ideal for resource-constrained environments.

Key Features:

Header-only library with no dependencies
No code generation required
Supports both reading and writing protobuf messages
Compatible with C++11 and later standards

Use Cases:

High-performance embedded systems with limited resources
Parsing protobuf data in performance-critical applications
C++ projects needing protobuf support without heavy dependencies

Alternatives:

protobuf – Official Google library with code generation, larger footprint but more features
nanopb – Lightweight C library for embedded systems, but less C++-native than protozero
