Description

/// Checks if the elements of this iterator are partitioned according to the given predicate, /// such that all those that return true precede all those that return false. fn is_partitioned

(mut self, mut predicate: P) -> bool where Self: Sized, P: FnMut(Self::Item) -> bool,

feature = "iter_is_partitioned"

ref: #62278

Unresolved questions

• Do we want this function at all? (Motivating use cases would be useful.)
• Would is_sorted_by_key already cover all use cases?
