  = note: `#[warn(clippy::unnecessary_find_map)]` 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?

Complexity. The intent is also clearer if only a single operation is being performed.

Code that does something simple in a complicated way. Warns by default.

How to fix it

Clippy does not fix this one automatically. Change the code by hand:

Flagged

let _ = (0..3).find_map(|x| if x > 2 { Some(x) } else { None });

// As there is no transformation of the argument this could be written as:
let _ = (0..3).find(|&x| x > 2);

Write this instead

let _ = (0..4).find_map(|x| Some(x + 1));

// As there is no conditional check on the argument this could be written as:
let _ = (0..4).map(|x| x + 1).next();

Turn it off, or on

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

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

[lints.clippy]
unnecessary_find_map = "allow"

cargo clippy -- -A clippy::unnecessary-find-map

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.
