What problem does it solve?

Rust APIs often suffer from unsafe ergonomics and inconsistent design decisions that hinder safety, readability, and maintainability.

Core Features & Use Cases

• Builder Pattern: enable complex configurations with fluent, type-safe builders.
• Newtype Pattern: enforce semantic meaning and prevent mixing values across domains.
• Trait Design & Generics: craft flexible, reusable APIs with trait-based abstractions and generic bounds.
• Sealed Traits: restrict external implementations to preserve invariants.
• Type-safety Focus: encode invariants at compile time for safer APIs.

Quick Start

Apply these patterns in your Rust crate by refactoring constructors to builders, replacing primitive params with newtypes, and using traits to define stable, extensible interfaces.
