Enum DirectiveUsed

Source

pub enum DirectiveUsed {
    Yes,
    No,
    Checked,
}

Expand description

When a directive is set to “ignore”, it means a normally-active tidy lint is now ignored. This can be bad, if it’s ignored for no reason, so we track whether the ignore is actualy ignoring something.

Variants§

§

Yes

A lint is ignored, and something used that fact. i.e. A lint would’ve been emitted if it wasn’t ignored.

§

No

A lint is ignored but nothing yet used this ignore.

§

Checked

For drop-bomb behavior: a directive is ignored, and we’ve checked whether it was used or not. Directives panic on drop if they aren’t checked, to ensure we always emit a lint when a directive is uselessly ignored
