[−][src]Module syntax::mut_visit
A MutVisitor represents an AST modification; it accepts an AST piece and and mutates it in place. So, for instance, macro expansion is a MutVisitor that walks over an AST and modifies it.
Note: using a MutVisitor (other than the MacroExpander MutVisitor) on an AST before macro expansion is probably a bad idea. For instance, a MutVisitor renaming item names in a module will miss all of those that are created by the expansion of a macro.
