Rust for Python Programmers

Class Duration

35 hours of live training delivered over 5-10 days to accommodate your scheduling needs.

Student Prerequisites

• Strong working proficiency in Python
• Comfort with packaging (pip, uv, poetry) and virtual environments
• Familiarity with type hints and mypy/pyright is helpful but not required

Target Audience

Python developers and ML/data engineers adding Rust to their toolkit — for performance-critical hot paths, native Python extensions, async services, CLIs, or memory-safe rewrites of legacy components. Particularly relevant for teams shipping LLM applications who need a fast, safe runtime for the parts of the system Python isn't well suited to.

Training Materials

All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples.

Software Requirements

A free GitHub account, the latest stable Rust toolchain installed via rustup (Rust 1.96+ on the 2024 edition), Python 3.12+, Visual Studio Code or another supported editor with the rust-analyzer extension, and an AI coding assistant of choice (GitHub Copilot, Cursor, or Claude Code). A cloud-based environment can be provided if local installation is restricted.

Introduction: Rust from a Python Perspective

• What Rust is and where it fits relative to Python
