From 1519ca99d8020f4d2e4fb04a3eb425b97e457d18 Mon Sep 17 00:00:00 2001 From: moxian Date: Tue, 19 Oct 2021 00:03:51 +0000 Subject: [PATCH] Tiny tweak to Iterator::unzip() doc comment example. It's easier to figure out what it's doing and which output elements map to which input ones if the matrix we are dealing with is rectangular 2x3 rather than square 2x2. --- library/core/src/iter/traits/iterator.rs | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/library/core/src/iter/traits/iterator.rs b/library/core/src/iter/traits/iterator.rs index f53d6cac7ed..d957a7527cf 100644 --- a/library/core/src/iter/traits/iterator.rs +++ b/library/core/src/iter/traits/iterator.rs @@ -2837,12 +2837,12 @@ pub trait Iterator { /// Basic usage: /// /// ``` - /// let a = [(1, 2), (3, 4)]; + /// let a = [(1, 2), (3, 4), (5, 6)]; /// /// let (left, right): (Vec<_>, Vec<_>) = a.iter().cloned().unzip(); /// - /// assert_eq!(left, [1, 3]); - /// assert_eq!(right, [2, 4]); + /// assert_eq!(left, [1, 3, 5]); + /// assert_eq!(right, [2, 4, 6]); /// /// // you can also unzip multiple nested tuples at once /// let a = [(1, (2, 3)), (4, (5, 6))];
