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
!
