Struct StructuralVisitorView

pub struct StructuralVisitorView<'a, D> { /* private fields */ }

Recursive visiting and default child descent for a dispatcher.

Pass the handler’s self to visit methods to recurse with the same state.

Implementations

impl<D> StructuralVisitorView<'_, D>

pub fn def_region_kind(&self) -> DefRegionKind

pub fn with_def_region_kind<R>( &mut self, kind: DefRegionKind, callback: impl FnOnce(&mut Self) -> R, ) -> R

Run operations under a scoped definition region. An enclosing Pattern wins; the previous region is restored on all exits.

pub fn visit<'input, T>( &mut self, dispatch: &mut D, value: T, ) -> Result<Option<VisitInterrupt>>

where T: Into<AnyView<'input>>,

Visit a value through the dispatcher.

pub fn default_visit<'input, T>( &self, dispatch: &mut D, value: T, ) -> Result<Option<VisitInterrupt>>

where T: Into<AnyView<'input>>,

Run Base default descent, using registered hooks or reflected fields by default. Children re-enter the dispatcher; the current value does not.
