RS.CLIPPY.BOOL_ASSERT_COMPARISON

Using a boolean as comparison value in an assert_* macro when there is no need

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_assert_comparison. Copyright ©2025 The Rust Team. All rights reserved.

What it does

This lint warns about boolean comparisons in assert-like macros.

Why is this bad?

It is shorter to use the equivalent.

Example

assert_eq!("a".is_empty(), false);
assert_ne!("a".is_empty(), true);

Use instead:

assert!(!"a".is_empty());
