Return the inner [`SubclassOfInner`] value wrapped by this `SubclassOfType`.

Specify files to be created in the `site-packages` mock directory

Build the test server

Return `true` if the `Expr` contains an expression that appears to include a side-effect (like a function call). Accepts a closure that determines wh

Returns the new content for an insertion or deletion.

Infers the type of an `expression` that is guaranteed to be in the same file as the calling query. This is a small helper around [`infer_expression_t

Returns `true` if there are no fixes in the map.

Returns an iterator over the fixes in the map, along with the file path.

Returns an iterator over the patterns and keywords in source order.

Parses the content and returns its AST

Returns the comment's preceding node. The direct child node (ignoring lists) of the [`enclosing_node`](DecoratedComment::enclosing_node) that precede

Pushes the given line as part of this code example.

Returns the re-mapped position or `position` if no mapping exists.

Run the benchmark using `hyperfine`.

A convenient wrapper around [`check_path`], that additionally asserts that fixes converge after a fixed number of iterations.

Add a workspace to the test server with the given root path.

Walk the `NewTypeBase` chain to find the underlying non-newtype `Type`. There might not be one if this `NewType` is cyclical, and we fall back to `obj

Returns the position encoding that was negotiated during initialization.

Returns whether this is a nominal instance of a particular [`KnownClass`].

Returns whether this is a known class.

Loads a reference to the parsed module. Note that holding on to the reference will prevent garbage collection of the AST. This method will reparse th

Similar to [`Type::member`], but allows the caller to specify what policy should be used when looking up attributes. See [`MemberLookupPolicy`] for mo

Pushes a new [`Binding`] and returns its [`BindingId`].

Generic function to remove arguments or keyword arguments in function calls and class definitions. (For classes, `args` should be considered `bases`.)

Returns an iterator over all [`NodeId`] ancestors, starting from the given [`NodeId`].

Return `true` if `ty`, or any of the types contained in `ty`, match the closure passed in. The function guards against infinite recursion by keeping

Returns an iterator over the bytes of the concatenated bytestring.

Closes the virtual file.

Helper function to create a directory and all parent directories

Returns an [`Iterator`] over the current statement hierarchy, from the current [`Stmt`] through to any parents.

Return the positional argument at the given index, or `None` if no such argument exists.

Returns the node following the comment. The direct child node (ignoring lists) of the [`enclosing_node`](DecoratedComment::enclosing_node) that follo

Returns `true` if the text only consists of ASCII characters

Returns `true` if a string is a valid Python identifier (e.g., variable name).

Returns `true` if a function definition is an `@overload`.

Returns `true` if the given name matches any of the ignored patterns.

Add a primary annotation with a message. If the message is empty, then an annotation without any message be created. See the docs on `TestEnvironmen

Returns the [`QualifiedName`] of the imported name (e.g., given `from foo import bar as baz`, returns `["foo", "bar"]`).

Returns the [`TextRange`] for the diagnostic.

Generate source code from a [`Stmt`].
