purescript-erl-sets

A PureScript library for Erlang sets, using an FFI to Erlang's sets module for efficiency.

Installation

Add erl-sets to your spago.yaml file and spago install.

dependencies:
  - erl-sets

Usage

import Prelude
import Erl.Data.Set as Set

mySet :: Set.Set Int
mySet = Set.fromFoldable [1, 2, 3, 3, 4]

-- Set.member 3 mySet == true
-- Set.size mySet == 4

API Documentation

The module Erl.Data.Set provides an API that mirrors the standard Data.Set module from purescript-ordered-collections.

This implementation uses a Foreign Function Interface (FFI) to Erlang's sets module for performance. The module uses Erlang's term equality as opposed to the Eq class.

Development

To build the project and run the tests, use the following commands:

spago build
spago test
