}Expand description
Immutably walks the entire AST
Each method acts as a customization point.
There are a set of default implementations for enums
under the name or_visit_*,
provided for ease of use.
For all other nodes, traversal is explicit.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
