Example not working about ferrumfix HOT 2 CLOSED

Hi! Thank you for reading through the code and providing feedback!

I decided to momentarily remove fefix::session::FixConnection because it's not ready yet. Mind you, it's the single feature I'm most dedicated to, so it'll be back in some future version once I've made some progress. Before 0.7.0, FixConnection was always there yet broken and I think it's better to be more direct in showing my users what I consider to be ready to use and what is not. This is also the reason why some examples using it may be momentarily commented out!

As for async_trait - you're right, it would be so much simpler. Unfortunately, it costs one allocation per function call which is quite expensive. For the foreseeable future, the Backend / Application type (I haven't settled on a name yet) will not be async and users will have to either use a thread pool or e.g. explicitly enter a Tokio Runtime. It's a bit annoying, but it'll work and it will flexible enough for almost any use case.

Long term, we want to provide a middleware API so that users can build abstractions on top of Backend. Some examples might be:

• Log all incoming and outgoing messages.
• Store all messages in a DB.
• Add some FIX field in the header of all outgoing messages, before they're sent out.
• Build your application against an AsyncBackend wrapper, rather than directly against Backend.

The specific pattern via channels that you mentioned will be possible!

Thank you for offering to help! I don't think I'll be able to accept contributions to the core at the moment (it takes a lot of energy and things are mature enough yet), but our documentation could definitely use some help. You can try to build docs on your machine with RUSTDOCFLAGS="--cfg doc_cfg" cargo +nightly doc --all-features --open. You'll get warnings about missing documentation items and you can start from there. You can get a sense of what kind of writing style I'm going for by looking at what I've written so far.

@neysofu Sounds all good. This project definitely has a lot of potentials and I cannot wait to see how great this can become. In the meantime, since I'm currently looking for a ready-to-use library for FIX engines, I'll use https://github.com/jbendig/fix-rs for a simple poc product I'm working on. Hopefully, this project becomes production ready so that I'll be able to swith FIX library to this in the near future.

Thanks again for staring on this project.
