A FIX message codec library written by Rust

Hi, I have around 4 years of experience with bank services and 9 years with the finance system (hopefully will be more). During lunar new year, I spent a little time with a Rust project for encoding and decoding FIX messages (Financial Information eXchange).

I try to build a high-performance, zero-copy codec library. The current version is target to version FIX 4.2 and 4.4, which I frequently deal with. I'm looking for feeback for my library make sure everything good enough, my first Rust library!!!

Thanks for your time to take a look!
