Variants

No

Do not issue the lint.

SimplePath(NodeId)

This lint applies to some arbitrary path; e.g., impl ::foo::Bar. In this case, we can take the span of that path.

UsePath

This lint comes from a use statement. In this case, what we care about really is the root use statement; e.g., if we have nested things like use a::{b, c}, we care about the use a part.

Fields of UsePath

root_id: NodeIdroot_span: Span

QPathTrait

This is the "trait item" from a fully qualified path. For example, we might be resolving X::Y::Z from a path like <T as X::Y>::Z. The path_span is the span of the to the trait itself (X::Y).

Fields of QPathTrait

qpath_id: NodeIdqpath_span: Span
