Parse a stringified type annotation as an AST expression, e.g. `"List[str]"` in `x: "List[str]"` This method is a wrapper around [`ruff_python_parser

The full path that this entry represents.

Returns the path to the configuration file.

Format the expressions as a PEP 604-style union.

Returns the primary message for this diagnostic. A diagnostic always has a message, but it may be empty.

Returns a reference to the primary span of this diagnostic.

Pushes a *leading* part for `key`.

Push a new marker to the sourcemap. ## Panics If `offset` is less than previous markers.

Loads this constraint set into a new builder, invokes a callback with that builder, and returns the result. This is more efficient than [`ConstraintS

A `str` representation of the quotes used to start and close. This does not include any prefixes the string has in its opener.

Returns the range of the statements comprising the basic block at the given index

Registers a new pending request.

Expand this complement to the enum literals that remain possible.

Return a [`DiagnosticGuard`] for reporting a diagnostic. The guard derefs to a [`Diagnostic`], so it can be used to further modify the diagnostic bef

Resolve the [`TargetVersion`] to use for linting. This method respects the per-file version overrides in [`LinterSettings::per_file_target_version`]

Runs the directory traversal and calls the passed `builder` to create visitors that do the visiting. The walker may run multiple threads to visit the

Get the document settings associated with this query.

Returns an iterator over all bindings that the given binding shadows, including itself.

Returns the single `CallableBinding` if this is not a union or intersection.

When set, symbols that aren't in scope but available in the environment will NOT be included. Auto-import is enabled by default. So one must opt into

Skips the next `count` bytes. ## Panics - If `count` is larger than the remaining bytes in the input stream. - If `count` indexes into a multi-byte c

Return a [`ParenthesizableWhitespace`] containing a single space.

Takes the salsa events.

Look up a generic [`KnownClass`] in its canonical module and return a [`Type`] representing a specialization of that class. If the class cannot be fo

Traverse a "union" type annotation, applying `func` to each union member. Supports traversal of `Union` and `|` union expressions. The function is c

Return the metaclass of this class, or an error if the metaclass cannot be inferred.

Get the version of document selected by this query.

Get the path for the document selected by this query, ignoring whether the file exists on disk. Returns the URI's path if this is an unsaved (untitle

Add a "library" root to this test case.

Add a [`Binding`] to the current scope, bound to the given name.

Add a `from __future__ import annotations` import.

Add a subdiagnostic to `diagnostic` that explains why a certain Python version was inferred. ty can infer the Python version from various sources, su

Adds a new predicate to the list of all predicates, but does not record it. Returns the predicate ID for later recording using [`SemanticIndexBuilder:

Add the given folding range if it spans multiple lines.

Record an expression that needs to be a Salsa ingredient, because we need to infer its type standalone (type narrowing tests, RHS of an assignment.)

Safely adjust the indentation of the indented block at [`TextRange`]. The [`TextRange`] is assumed to represent an entire indented block, including t

Compute the subject and binding types produced by a successful pattern. `subject_ty` is the type of the value reaching this pattern node. Structural

Applies the options from the configuration files to the project's options. This includes: The user-level configuration

The full debug text between the `{` and the conversion / `format_spec` / `}`.

Assert that the Salsa query described by the generic parameter `C` was executed at least once with the input `input` in the history span represented b

Calculates the [`PathBounds`] that represent the valid solutions for when `self` is constraint-set assignable to `target`.

Returns `true` if the parser is at a soft keyword token.

Resolves this member type and binds member-local `Self` occurrences to `self_type`.

Return the [`CellOffsets`] for the concatenated source code corresponding the Jupyter notebook.

Return the [`Definition`] of the class enclosing this method, given the method's body scope, or `None` if it is not a method.

Look up a class-level member by iterating through the MRO.

Return the suppressed codes as strings

Returns `true` if this type contains a `Self` type variable.
