Invokes a closure, capturing and returning the cause of an unwinding panic if one occurs. ### Thread safety This is implemented by installing a cust

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

Returns the default specialization for this class. For static classes, this applies default type arguments. For dynamic classes, this returns a non-g

Returns the files belonging to this project.

Returns the [`FileRange`] of the function's name.

Looks up a lint by its name.

Returns `true` if this is the id of the global scope

Returns `true` if this is a keyword-variadic parameter.

Returns `true` if the expression is a literal expression. A literal expression is either a string literal, bytes literal, integer, float, complex num

Returns the relative path as specified by the user.

Infer the combined type from an iterator of bindings, and return it together with boundness information in a [`Place`]. The type will be a union if t

Returns the [`ScopedPlaceId`] of the place expression.

Compute the overall effective return type of this `ConstructorBinding`.

Set the value of the `AtomicNodeIndex`.

Set the fix for this diagnostic.

Returns an iterator over the fixes in the map.

The code that is ignored by the `noqa` directive.

Returns an iterator over the direct child scopes of `scope`.

Introspects this diagnostic and returns what kind of "primary" message it contains for concise formatting. When we concisely format diagnostics, we l

Returns the underlying test DB.

Current exit block, which may change during construction

Get the initialization result

Return a new tuple-spec builder that reflects the intersection of this tuple and another tuple, or `None` if the intersection is impossible (e.g., two

Returns whether two bound typevars represent the same occurrence, regardless of e.g. differences in their bounds or constraints due to materialization

Return the display kind of the function-like node.

Length of this annotation as displayed in the stderr output

If this type is a class instance, returns its class.

Build a declared type from a [`DeclarationsIterator`]. If there is only one declaration, or all declarations declare the same type, returns `Ok(..)`.

Expand this complement to the union of enum literals that remain possible.

Returns the [`Tokens`] for the parsed type annotation if the checker is in a typing context or the parsed source code.

Calls `self`. Returns a [`CallError`] if `self` is (always or possibly) not callable, or if the arguments are not compatible with the formal parameter

Return the numeric value for this [`LineLength`]

Write the transformed source file to the given writer. For Jupyter notebooks, this will write out the notebook as JSON.

Adds a member to the table or updates the flags of an existing member if it already exists. Members are identified by their expression, which is hash

Return `true` if any base class matches a [`QualifiedName`] predicate.

Returns a slice containing the remaining comments.

Classify a function based on its scope, name, and decorators.

Sends a `textDocument/completion` request for the document at the given URI and position.

Returns the node with a minimal range that fully contains `range`. If `range` is empty and falls within a parser *synthesized* node generated during

Returns an iterator over all scopes, starting from the current [`Scope`].

Returns the default registry with all known semantic lints.
