Thanks for your contribution @xoac !

Are you sure you wanted to update just the example?

Besides:
For any nats cli experience, I would stick to https://github.com/nats-io/natscli , which is a very powerful tool.

For any code-related work, I would use async-nats crate.

Hi @Jarema it works well and it's simpler CLI for testing than natscli. The code of rust version is shorter than the README.md of natscli and I don't need to install yet another language compiler. I just pushed PR because I wanted to print the json format of messages that I publish with async-nats ;)

What else you want update here?

I meant that this is just a short example how library can be used :).

Just FYI - you don't need Go compiler to work with CLI, nor read much of the docs. it's the same nats pub and nats sub.
It's available as released binary and in some package managers.

As said, as this is just an example, I have no problems with merging it if that helps you.

LGTM

It's short and simple - exactly what I am looking for and I was able to use this in 2min when I wasn't able to install natscli in 2min 乁(⫑ᴥ⫒)ㄏ (no golang, not included with my distro. I don't download libraries that can't be updated automatically). I am not saying that natscli is bad or sth - but I use rust on daily basic and this is just simpler for me. I guess for golang people it would be easier just go with natscli.
