gary

A Gleam interface to Erlang's array module, for sparse, efficiently-implemented functional arrays. 🐝

gleam add gary

import gary/array

pub fn main() {
  list.range(1, 10)
      |> array.from_list(default: -99)
      |> array.drop(at: 5)
      |> result.map(array.map(_, fn(_, v) { 2 * v }))
      |> result.map(array.to_list)
  // = Ok([2, 4, 6, 8, 10, -198, 14, 16, 18, 20])
}
