pub(crate) fn push( &mut self, attrs: &[Attribute], is_crate_node: bool, source_hir_id: Option<HirId>, ) -> BuilderPush
Pushes a list of AST lint attributes onto this context.
This function will return a BuilderPush
object which should 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 attributes 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
!
Sourcepub(crate) fn pop(&mut self, push: BuilderPush)
pub(crate) fn pop(&mut self, push: BuilderPush)
Called after push
when the scope of a set of attributes are exited.
