Expand description
A MutVisitor represents an AST modification; it accepts an AST piece 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.

Traits§
- MutVisitor
- Each method of this trait is a hook to be potentially
overridden. Each method’s default implementation recursively visits
the substructure of the input via the corresponding
walkmethod; e.g., thevisit_itemmethod by default callsvisit_mut::walk_item. - Walk
