linkerd2-proxy VS prost

Oh, there are many - https://lib.rs/crates/sfz is a simple one. If you're looking to proxy to something else, there's https://github.com/linkerd/linkerd2-proxy, etc.

Linkerd: Meant to be used in a kubernetes deploy, but the readme mentions possibilities of using it elsewhere.

I am really curious about Rust after looking for API proxies (in particular Linkerd2 - https://github.com/linkerd/linkerd2-proxy). Can anyone share her/his experience on going from Python to Rust? (bonus point if related to API :lol:)

Here is production ready service mesh using pre-1.0 crates: https://github.com/linkerd/linkerd2-proxy/blob/main/linkerd2-proxy/Cargo.toml

I know linkerd proxy is written in rust. You could look at that project to help get you started. Be aware that their use case is for very lightweight proxies inside of clusters so it might not fit your goals exactly.

Linkerd--a service mesh for Kubernetes--has featured a proxy written in Rust (since ~2017), but its control plane has been implemented entirely in Go... until now!

Its also heavily in linkerd-proxy https://github.com/linkerd/linkerd2-proxy which is a service mesh for kubernetes.

A build.rs file is used to generate Rust bindings at build-time.

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.

You could use Protocol buffers to define a message type, then use prost to generate encoding/decoding code for that type.

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

Hi r/rust, I have a question regarding tonic-build (or prost-build).

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.

Note: one additional key feature currently missing from Prost is Proto2 extensions.
