Architecture & Design

The mental model behind Rust architecture: the crate graph is the dependency graph, error strategy is a decision made early, and the type system encodes domain rules so illegal states cannot compile.

Bootstrap or restructure a Rust project with this architecture checklist. Define toolchain, layout, dependencies, error handling, and testing strategies.

Learn to design robust error types across your Rust codebase. Implement precise domain enums, map transport errors, and aggregate context effectively.

Design Rust applications with robust configuration and features. Learn to separate compile-time features from runtime settings, validate inputs, and manage secrets.

Perform a Rust codebase health audit. Use this checklist to identify issues in build, dependencies, code quality, architecture, and operations.

Learn best practices for Rust architecture, covering boundaries, API design, workspace management, and operations to build maintainable and scalable systems.
