# Rust Developer Guide

> A guided path for Rust developers learning how Sifr exposes ownership, Result, Option, generated Rust, and native builds through Python-shaped syntax.

If you know Rust, Sifr's safety model will feel familiar, but the source language keeps Python-shaped syntax. Use this path to map ownership, typed errors, generated Rust, and native binaries back to concepts you already know.

## Learning Sequence

1. Build the mapping: [Rust Concepts in Sifr](/guides/rust-developers/rust-concepts).
2. Inspect generated code: [Check and Emit](/cli/check-emit).
3. Learn source-level ownership: [Ownership and Mutability](/language/ownership).
4. Review typed failures: [Error Handling](/language/error-handling).
5. Understand structured async: [Concurrency Overview](/language/concurrency).
6. Expose Rust-backed APIs: [Rust Interop](/rust-interop).
7. Ship a binary: [Build and Run](/cli/build-run).

<Note>
  Sifr is not a Rust macro language. The generated Rust is an implementation target you can inspect, while the Sifr source model remains the language contract.
