Rust Functional

Open-source Rust projects categorized as Functional

Top 6 Rust Functional Projects

  • enso

    Hybrid visual and textual functional programming.

    Project mention: Show HN: Ezno, a TypeScript checker written in Rust, is now open source | | 2023-06-07

    I think Enso is already taken by a YC company [0]. Could get confusing.


  • gluon

    A static, type inferred and embeddable language written in Rust.

    Project mention: Gluon is a static, type inferred and embeddabble language written in Rust | | 2023-07-01

  • tao

    A statically-typed functional language with generics, typeclasses, sum types, pattern-matching, first-class functions, currying, algebraic effects, associated types, good diagnostics, etc. (by zesterer)

    Project mention: What backwards-incompatible changes would you make in a hypothetical Rust 2.0? | /r/rust | 2023-04-19

    If you want some prior work on this, I've implemented effect-objects-as-return-values in my own language Tao, using uniqueness types. There's still work to be done, but I think it's sufficient as a proof of concept that this approach is viable without type soup.

  • kcl

    A constraint-based record & functional language mainly used in configuration and policy scenarios.

    Project mention: KCL: A Python Like Configuration Programming Language written in Rust and Python | /r/Python | 2023-08-22

    Rust Ver. here

  • pen

    The parallel, concurrent, and functional programming language for scalable software development (by pen-lang)

  • letlang

    Functional language with a powerful type system.

    Project mention: Letlang — Roadblocks and how to overcome them - My programming language targeting Rust | /r/programming | 2023-06-07

    That works for any types (except the functional types), and even the generic ones. During code generation, I create structs that implement the Type trait.
