rust-const

What problem does it solve?

This Skill helps developers move runtime checks and invariants to compile-time, ensuring greater safety, performance, and correctness in Rust code.

Core Features & Use Cases

• Const Generics: Define types and functions that are generic over compile-time constants (e.g., array sizes).
• Const Functions (const fn): Write functions that can be evaluated at compile time, enabling zero-cost computations.
• Compile-Time Validation: Use assert! within const fn to enforce constraints during compilation.
• Use Case: Optimize a fixed-size buffer implementation by using const generics for its size, ensuring it's checked at compile time and has no runtime overhead.

Quick Start

Use the rust-const skill to demonstrate a const fn for calculating Fibonacci numbers.
