Trait Implementations

impl<F: FnMut(&mut Block), G: FnMut(&mut Statement)> VisitBodyMut for BlockVisitor<F, G>

fn exit_llbc_block(&mut self, x: &mut Block)

Called when finished visiting a $ty (unless visit_$ty is overriden).

fn enter_llbc_statement(&mut self, x: &mut Statement)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn visit<'a, T: BodyVisitable>( &'a mut self, x: &mut T, ) -> ControlFlow<Self::Break>

Visit a visitable type. This calls the appropriate method of this trait on x (visit_$ty if it exists, visit_inner if not).

fn visit_by_val<T: BodyVisitable>( self, x: &mut T, ) -> ControlFlow<Self::Break, Self>

Convenience alias for method chaining.

fn visit_by_val_infallible<T: BodyVisitable>(self, x: &mut T) -> Self

where Self: Visitor<Break = Infallible> + Sized,

Convenience when the visitor does not return early.

fn visit_inner<T>(&mut self, x: &mut T) -> ControlFlow<Self::Break>

where T: for<'s> DriveMut<'s, BodyVisitableWrapper<Self>>,

Visit the contents of x. This calls self.visit() on each field of T. This is available for any type whose contents are all #trait_name.

impl<F: FnMut(&mut Block), G: FnMut(&mut Statement)> Visitor for BlockVisitor<F, G>

type Break = Infallible

The type used for early-return, if the visitor supports it. Use an empty type like std::convert::Infallible if the visitor does not short-circuit.
