Pydantic V2 rewritten in Rust is 5-50x faster than Pydantic V1
Maybe I&#x27;m just a little skeptical today, but I&#x27;m not super enthusiastic about this.<p>1.) Adding another language significantly increases complexity in general. Now I see several packages (pydantic, pydantic-core, pydantic-settings). Issues can crop up in either language, or in the translation.<p>2.) Your typical users are python developers, many which don&#x27;t know rust, and therefore would be unable&#x2F;unwilling to help contribute or help debug issues. Debugging an issue with pure python is easier (ctrl-click in my IDE will take me to the code and I can look and see what is going on, add print statements, etc, even in external libraries).<p>3.) At least in my use cases (and we use pydantic quite a bit), performance increases there will be negligible compared to things like data transfer (network, db) and the rest of my code that&#x27;s written in python.<p>Anyway, I do love pydantic, and hope this is just a drop-in replacement and I don&#x27;t have too many issues.
