type Result = ()

The result type of the visit_* methods. Can be either (), or ControlFlow<T>.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
