pub fn main() {
 fswalk.builder()
   |> fswalk.with_path("test/fixture")
   |> fswalk.with_entry_filter(fn(entry) {
     !string.contains(does: entry.filename, contain: "ignore")
   })
   |> fswalk.with_traversal_filter(fn(entry) {
     !string.contains(does: entry.filename, contain: "build")
   })
   |> fswalk.walk
   |> iterator.map(fn(it) {
     let assert Ok(entry) = it
     entry.filename
   })
   |> iterator.to_list
   |> list.sort(string.compare)
   |> should.equal([
     "test/fixture/a", "test/fixture/b", "test/fixture/b/c", "test/fixture/b/c/d",
   ])
