Std.Text.unfold

1 declaration

fn

unfold: Int -> S -> fn(S) -> Option[(Char, S)] -> Str

This is a callable function.

What it does

Text grown from a seed until the step answers None.

The step count is bounded because a strict language cannot recover from a

step that never stops.

Read the signature

  • The text after the name is the type checked by Pudu.
  • Read arrows from left to right: inputs come first, and the final type is returned.
  • Names inside [ ] are type arguments, such as the item type held by a collection.
  • Option holds Some(value) or None when no value is available.
