RS.CLIPPY.BOOL_COMPARISON

Comparing a variable to a boolean, e.g., `if x == true` or `if x != true`

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

What it does

Checks for expressions of the form x == true, x != true and order comparisons such as x < true (or vice versa) and suggest using the variable directly.

Why is this bad?

Unnecessary code.

Example

if x == true {}
if y == false {}

use x directly:

if x {}
if !y {}
