noproto

No-std, no-alloc protocol buffers (protobuf) implementation in Rust, for embedded systems. Optimized for binary size and memory usage, not for performance.

Status: very experimental ☢️

Features

Implemented:

Derive macros.
heapless::Vec, heapless::String impls.
optional
repeated
oneof
enum

Not implemented (yet?):

Impls for alloc containers (goal is to be no-alloc, but we could still have them optionally).
Some types (see below)
Impls for &[T] for repeated fields (only doable for writing, not reading)
Tool to compile .proto files into Rust code.
Maps
Deprecated field groups.
