Is the symbol defined in this scope, vs referring to some enclosing scope? There are three common cases where a name refers to an enclosing scope: 1

Return `true` if the given `Expr` is a potential logging call. Matches `logging.error`, `logger.error`, `self.logger.error`, etc., but not arbitrary `

Returns `true` if preview mode is enabled.

Return `true` if `other` is present in this class's MRO.

Returns a tuple spec describing the elements that are produced when iterating over `self`. This method should only be used outside of type checking b

Load the current value of the `AtomicNodeIndex`.

Lookup a qualified attribute in the current scope. For example, given `["Class", "method"`], resolve the `BindingKind::ClassDefinition` associated wi

Iterate over the MRO of this base

Construct a path to a Jupyter notebook in the `resources/test/fixtures/jupyter` directory.

Returns the inferred type of the class member named `name`. Only bound members or those marked as `ClassVars` are considered. You must provide the `i

Adds parentheses and indents `content` if it doesn't fit on a line.

Consumes the [`Parser`] and returns the parsed [`Parsed`].

Whether to enable preview behavior or not.

Find all project files in a set of paths, following configured include/exclude settings.

Promote (possibly nested) literals to types that these literals are instances of. Note that this function tries to promote literals to a more user-fr

Pushes a *dangling* part for `key`

Generate a `Fix` to remove the specified imports from an `import` statement.

Return the [`QualifiedName`] of the value to which the given [`Expr`] is assigned, if any. For example, given: ```python import asyncio loop = async

Creates a specialization of this generic context. Panics if the length of `types` does not match the number of typevars in the generic context. You m

Takes the salsa events.

Creates a new token that uses this source.

Same as `try_call_dunder`, but allows specifying a policy for the member lookup. In particular, this allows to specify `MemberLookupPolicy::MRO_NO_OBJ

Returns an _owned_ (i.e. salsa-cached) constraint set that describes when `self` is constraint-set assignable to `target`.

Returns a new `Span` with the given optional `range` attached to it.

Returns a new `Span` with the given `range` attached to it.

Returns a new bound typevar instance without any `ParamSpec` attribute set. This method will also remove any upper bound that was set by `with_params

Return all matching rules, regardless of rule group filters like preview and deprecated.

Apply a series of fixes.

Combine the project options with the CLI options where the CLI options take precedence.

Returns the inner fixed-length tuple if this is a `Tuple::Fixed` variant.

Returns the prefix parameters and bound `ParamSpec` if this parameter list is either `P` or `Concatenate[<prefix-params>, P]`. For the narrower bare-

Return `Some(literal)` if the string only consists of a single `StringLiteral` part (indicating that it is not implicitly concatenated). Otherwise, re

Searches the token(s) at `offset`. Returns [`TokenAt::Between`] if `offset` points directly inbetween two tokens (the left token ends at `offset` and

Return `true` if the model is at the top level of the module (i.e., in the module scope, and not nested within any statements).

Returns all attribute assignments as scope IDs for a specific class body scope. Only call this when doing type inference on the same file as `class_b

Determine whether instances of this class are always truthy, always falsy, or have an ambiguous truthiness. Returns `None` for `KnownClass::Tuple`, s

Bumps the current token regardless of its kind and advances to the next token. # Panics If the parser is at end of file.

Returns the row number (1-based) in the cell (1-based) for the given row (1-based).

Check types for this constructor method, and then decide (based on the resolved return types) whether we should continue considering downstream constr

Clears the salsa events. ## Panics If there are any pending salsa snapshots.

Returns the indentation's visual width in columns/spaces. For docstring indentation, black counts spaces as 1 and tabs by increasing the indentation
