  = note: `#[warn(clippy::iter_skip_next)]` on by default

Real output of Clippy 0.1.99 (Rust 1.99) on the example below. Names and line numbers in yours will differ.

Does it matter?

.nth(x) is cleaner

Code that works but is not idiomatic Rust. Warns by default.

How to fix it

Clippy can fix this one for you: run cargo clippy --fix (add --allow-dirty if you have uncommitted changes). Review the diff before you commit.

Flagged

let some_vec = vec![0, 1, 2, 3];
let bad_vec = some_vec.iter().skip(3).next();
let bad_slice = &some_vec[..].iter().skip(3).next();

Write this instead

let some_vec = vec![0, 1, 2, 3];
let bad_vec = some_vec.iter().nth(3);
let bad_slice = &some_vec[..].iter().nth(3);

Turn it off, or on

Allow it where it does not fit your code, as narrowly as you can:

#[allow(clippy::iter_skip_next)]
fn my_function() { /* ... */ }

[lints.clippy]
iter_skip_next = "allow"

cargo clippy -- -A clippy::iter-skip-next

The [lints] table needs Rust 1.74 or newer. In a workspace, put it under [workspace.lints.clippy] and add [lints] workspace = true to each member.
