Summary

Clippy does not obey the lint_name = "allow" key under [lints.clippy] from Cargo.toml for certain lints, but does work as expected for others. The lints have to be silenced with #[allow(...)] instead.

In the example below, must_use_candidate obeys the [lints.clippy] settings, but wildcard_imports doesn't.

Other lints that don't obey [lints.clippy] that I have encountered:

• too_many_lines
• option_if_let_else

Reproducer

Cargo.toml:

[package]
name = "clippy-test"
version = "0.1.0"
edition = "2021"

[lints.clippy]
pedantic = "warn"

must_use_candidate = "allow"
wildcard_imports = "allow"

.cargo/config.toml:

[unstable]
lints = true

src/lib.rs:

mod foo {
    pub struct A;
}

// "usage of wildcard import" reported
use foo::*;

// "this function could have a `#[must_use]` attribute" not reported
pub fn a() -> A {
    A
}
