Return the [`LintContext`] for the current analysis. Note that you should always prefer calling methods like `settings`, `report_diagnostic`, or `is_

Creates a directory at `path`. All enclosing directories are created if they don't exist.

Returns all of the explicit base class types for this class. Note that when this is a namedtuple this always returns a sequence of length one corresp

Returns the `UnifiedFile` attached to this `Span`.

If the type is a union (or a type alias that resolves to a union), filters union elements based on the provided predicate. Otherwise, returns the typ
