List iterator

This module provides an iterator for lists that is accessible via List.iterM.

structure Std.Iterators.ListIterator (α : Type w) : Type w

The underlying state of a list iterator. Its contents are internal and should not be used by downstream users of the library.

• list : List α

@[inline]

def List.iterM {α : Type w} (l : List α) (m : Type w → Type w') [Pure m] : Std.IterM m α

Returns a finite iterator for the given list. The iterator yields the elements of the list in order and then terminates.

Equations

• l.iterM m = Std.Iterators.toIterM { list := l } m α
