Expand description

Creates new visitors.

A type implementing MakeVisitor represents a composable factory for types implementing the Visit trait. The MakeVisitor trait defines a single function, make_visitor, which takes in a T-typed target and returns a type implementing Visit configured for that target. A target may be a string, output stream, or data structure that the visitor will record data to, configuration variables that determine the visitor’s behavior, or () when no input is required to produce a visitor.
