$ show TheAlgorithms/Rust
TheAlgorithms/Rust is a large educational library of algorithm and data structure implementations in Rust, organized into over 20 modules covering sorting, searching, graph theory, dynamic programming, cryptography, machine learning, math, string processing, and more. The codebase is structured as a reusable Rust library crate with a flat module hierarchy, each module containing self-contained functions and types with extensive inline documentation and unit tests. It serves as a reference and learning resource rather than a production application, with many implementations based on textbook algorithms and well-known specifications (RFCs, NIST standards). The code demonstrates good engineering practices such as modular design, property-based testing with quickcheck, use of generics and traits for abstraction, and consistent test patterns. However, some modules show inconsistencies in naming and error-handling conventions, and the sheer variety of implementations means code quality varies. The repository is actively maintained with recent commits, automated CI/CD workflows, and dependency updates via Dependabot. While the implementations are pedagogical and not necessarily production-grade (e.g., simplified RSA, educational AES without side-channel resistance), they are functionally correct and well-documented, making this a valuable resource for learning algorithms in Rust.
The LLM identified 4 files worth highlighting for reuse:
Standalone AES implementation supporting 128/192/256-bit keys with ECB mode. Uses precomputed S-box, inverse S-box, and GF multiplication tables for performance. No external dependencies, making it easily extractable for use in other projects. Demonstrates careful low-level bit manipulation and optimization for educational purposes.
Shared test utilities for sorting algorithms, providing functions like `is_sorted`, `have_same_elements`, and `generate_random_vec`. This pattern reduces duplication across dozens of sorting implementations and can be reused in any Rust project requiring sorting verification. The code is simple, generic, and decoupled from any specific algorithm.
Defines a generic `Hasher` trait and implements HMAC based on that trait. This abstraction allows any hash function to be used with HMAC by implementing the trait, following a clean separation of concerns. The architecture is reusable for building other MAC constructions or hash-based utilities.
Weight unit conversion module using an enum of units and a generic `convert_weight` function that accepts both enum and string representations via the `IntoWeightUnit` trait. The pattern is consistent across conversion modules (temperature, pressure, volume) and can be extracted as a template for any unit conversion system. Uses precise physical constants and references authoritative sources.
