pub fn push(&mut self, attrs: &[Attribute]) -> BuilderPush

🔬 This is a nightly-only experimental API. (rustc_private)

Pushes a list of AST lint attributes onto this context.

This function will return a BuilderPush object which should be be passed to pop when this scope for the attributes provided is exited.

This function will perform a number of tasks:

• It'll validate all lint-related attributes in attrs
• It'll mark all lint-related attriutes as used
• Lint levels will be updated based on the attributes provided
• Lint attributes are validated, e.g. a #[forbid] can't be switched to #[allow]

Don't forget to call pop!
