Rewrite Sympy in rust

Hello, I was searching for a Rust crate that can perform symbolic manipulation similarly to Sympy in Python. However, I didn't find an alternative to Sympy implemented natively in Rust. Therefore, I am considering rewriting Sympy as a Rust crate.

The issue is that I don't have extensive experience writing code in Rust. As such, I would appreciate any recommendations you could provide on how I should approach this project. In particular, how would you suggest I get started in reimplementing Sympy's core functionality in a way that follows best practices for Rust development?
