Returns the generic context if this is a generic class.

The [`Indexer`] for the current file, which contains the offsets of all comments and more.

Iterates over the entries in the directory in name order.

Returns an iterator over all non-variadic parameters included in this [`Parameters`] node. The variadic parameters (`.vararg` and `.kwarg`) can never

Trims the indent of `rhs` by `self`. Returns `None` if `self` is not a prefix of `rhs` or either `self` or `rhs` use mixed indentation.

Return a constraint set indicating the conditions under which `self.relation` holds between `source` and `target`.

Send a `textDocument/diagnostic` request for the document at the given path.

When set, the module name for each symbol is included in the snapshot (if available).

Parses a single Python expression. This convenience function can be used to parse a single expression without having to specify the Mode or the locat

Resolves the [`ast::ExprName`] to the [`BindingId`] of the symbol it refers to, if any.

Run [`check_path`] on a snippet of Python code.

Stores a new file in the file system. The operation overrides the content for an existing file with the same normalized `path`. Enclosing directorie

Returns the [`OverloadLiteral`] representing this matching overload.

Resolves the [`ast::ExprName`] to the [`BindingId`] of the symbol it refers to, if it's the only binding to that name in its scope.

If `expr` is a reference to a builtins symbol, return the name of that symbol. Else, return `None`. This method returns `true` both for "builtin bind

Redact result_id values since they are hash-based and non-deterministic

Given an [`Expr`] that can be a [`ExprSubscript`][ast::ExprSubscript] or not (like an annotation that may be generic or not), return the underlying ex

Typed internally-visible signature for this function. This represents the annotations on the function itself, unmodified by decorators and overloads.

Compute the start position of the docstring's opening line

Given an [`Expr`] that can be callable or not (like a decorator, which could be used with or without explicit call syntax), return the underlying call

Returns the next line without advancing the cursor.

Set a custom message for the concise formatting of this diagnostic. This overrides the default behavior of generating a concise message from the main

Use a mock typeshed directory for this test case

Infer the type of a (possibly deferred) sub-expression of a [`Definition`]. Supports expressions that are evaluated within a type-params sub-scope.

Infer the type of a type expression.

Insert the type of this argument when inferred with the provided type context.

Returns whether this constraint set never holds

Create a [`NamedTupleSpec`] with the given fields.

Returns the token stream for `path` serialized as a string.

Call `func` over every `Expr` in `expr`, returning `true` if any expression returns `true`..

Returns the static class definition if this is one.
