Rust Language Fundamentals

2 min read

This chapter teaches the Rust language by mapping every concept to its Python equivalent. Each article shows the Python way first, then the idiomatic Rust way, then explains what changed and why.

Examples lean on MLOps scenarios — log parsing, config loading, data pipelines — so the context stays familiar.
