What problem does it solve?

Reduce wasteful computation in code by identifying and eliminating redundant work, such as repeated pure calls, loop-invariant calculations, and premature recomputation, to improve performance without changing behavior.

Core Features & Use Cases

• Detects redundant pure calls and hoists results to avoid repeated work.
• Identifies loop-invariant computations and proposes hoisting or caching strategies.
• Flags cache-like constructs that recompute on every access and suggests proper memoization or lazy evaluation.
• Works across languages with guidance to translate patterns (Rust examples provided).

Quick Start

Identify redundant computations in your Rust code and refactor to remove them while preserving determinism.
