Std.Text.Parse.count

1 declaration

fn

count: Int -> fn(Std.Text.Parse.Input) -> Result[(T, Std.Text.Parse.Input), Std.Text.Parse.Problem] -> fn(Std.Text.Parse.Input) -> Result[(Array[T], Std.Text.Parse.Input), Std.Text.Parse.Problem]

This is a callable function.

What it does

Exactly this many of a parser, and a problem if the input runs out first.

"Exactly n" is what separates a format from a shape that resembles it. An

ISO date is four digits, a dash, two digits, a dash, two digits; 2026-1-1

is a different thing wearing the same punctuation, and without this there is

no way to say so.

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.
  • Result makes success and recoverable failure part of the function's type.
