Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Add extra stuff to a “standard” encoding? Sure, why not
I actually went through all projects listed in [1] because I remember this very quirk. It turns out that there are many such libraries that have two variants of encode/decode functions, where the second variant prepends a varint length. In my brief inspection there do exist a few libraries with only the second variant (e.g. Rust quick-protobuf), which is legitimately problematic [2].
But if the project in question was indeed protobuf.js (see loeg's comments), it clearly distinguishes encode/decode vs. encodeDelimited/decodeDelimited. So I believe the project should not be blamed, and the better question would be why so many people chose to add this exact helper. Well, because Google itself also had the same helper [3]! So at this point protobuf should just standardize this simple framing format (with an explicitly different name though), instead of claiming that protobuf has no obligation to define one.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
The benchmark is not comparing apples to apples.
prost is the most widely used Protobuf implementation in Rust, maintained by the Tokio organization. prost generates structs and serialization/deserialization code for you.
easyproto according to GitHib Search is used only by two projects. easyproto provides primitives for serializing and deserializing Protobuf, and requires hand writing code to do both.
A fair comparison would be prost vs google.golang.org/protobuf, or easyproto vs parts of quick-protobuf.
In most cases you can make Go as fast as Rust, but from my experience writing performance-sensitive code in Go requires significantly larger time investment and overall requires deeper language expertise. Pebble (RocksDB replacement in Go by CockroachDB) is a good example of this, the codebase is littered with hand-inlined[1] functions, hand-unrolled loops and it's not[2] even using Go memory management for performance critical parts, it's using the C memory allocator and manual memory management.

Hey Rustaceans! Got a question? Ask here! (49/2022)!
You could use Protocol buffers to define a message type, then use prost to generate encoding/decoding code for that type.

grpc gateway
Thanks but that doesn't seems to support `json_mapping` , there is a draft available but not sure when it will get merged https://github.com/tokio-rs/prost/pull/558

[help] Tonic-build: how to generate generic service definition?
Hi r/rust, I have a question regarding tonic-build (or prost-build).
-
Unwrapping inner values from the enum more easily?
Currently, I'm making some stuff by using protobuf via prost. Maybe you know, protobuf v3 treats all fields as optional, so it is pain to unwrap every nested field.
- Best way to communicate between Rust and Go?
