How to encode messages?

[lz1998]

            let mut buf: Vec<u8> = Vec::with_capacity(200);
            frame.encode(&mut buf).unwrap();

Frame is generated from .proto file.

Did you bring the prost::Message trait in scope? Try adding a use prost::Message;.

Hi @fd,

Could you give me some performance advices?

My CPU profile shows that, it consumes a lot CPU when I call Message::encode_to_vec to serialize a protobuf object.

From the flame graph, Message::encoded_len and core::ptr::drop_inplace take long time.

What I want is to make HTTP requests via reqwest. I serialize the protobuf object to be the HTTP body.

Am I doing it right? Are there more efficient ways of do this?

BTW, I'm using prost 0.9.0.

Sorry, could you help? @LucioFranco

This isn't the right place to ask this question, you can open a separate discussion to look into it.
