Result

Use an ADT if you want to do vector math for everything other than WebGL in Elm!

It is more descriptive and has the best performance.

Implementations

elm-explorations/linear-algebra

This Package uses elm-explorations/linear-algebra and FFIs the webgl-mjs library.

However, for plain vector operations, this is the slowest implementation.

ADT

type Vec2
    = Vec2 Float Float

Record

type alias Vec2 =
    { x : Float
    , y : Float
    }

Tuple

type alias Vec2 =
    ( Float, Float )

Usage

1. nix-shell -p elmPackages.elm
2. elm reactor
3. Go to http://localhost:8000/benchmarks/Suite.elm

Results

Although in firefox the performance is ~25% slower for the ADT compared to tuples, they still have significant more advantages.
