Detailed Description

Signals derived from a valid AST of a file.

Provides information that can only be extracted from the AST to actions that can't access an AST. The signals are computed and updated asynchronously by the ASTWorker and thus they are always stale and also can be absent. Example usage: Information about the declarations used in a file affects code-completion ranking in that file.
