Closes #14278. Previously the type signatures of the ordering functions in `core::iter::order` took two iterators, but only if they were the same type of iterator. This commit loosens that restriction and allows different kinds of iterators (but with the same type of elements) to be compared.

They're currently very restricted as they only work with a single iterator type for both arguments, so, e.g.
let is_palindrome = order::equals(digits.iter(), digits.iter().rev());doesn't work.It should be easy to just add another
Iterator<A>parameter for the second argument.The text was updated successfully, but these errors were encountered:
