RS.CLIPPY.MANUAL_NEXT_BACK

Manual reverse iteration of `DoubleEndedIterator`

This checker is a Clippy lint created by The Rust Project Contributors. The documentation shown here is a copy of the original documentation for: manual_next_back. Copyright ©2025 The Rust Team. All rights reserved.

What it does

Checks for .rev().next() on a DoubleEndedIterator

Why is this bad?

.next_back() is cleaner.

Example

foo.iter().rev().next();

Use instead:

foo.iter().next_back();
