Lint attributes on crate imports and use statements have no effect and may indicate a misunderstanding or mistake in the code. This
can lead to confusion or unintended behavior.
Code examples
Noncompliant code example
#[deny(dead_code)]
extern crate foo;
#[forbid(dead_code)]
use foo::bar; // Noncompliant: Lint attributes are ineffective on imports.
Compliant solution
#[allow(unused_imports)]
use foo::baz;
#[allow(unused_imports)]
#[macro_use]
extern crate baz; // Compliant: Example with appropriate usage.
