impl Node for ExprRef

fn apply_children<'a, F: FnMut(&'a Self) -> VortexResult<TraversalOrder>>( &'a self, f: F, ) -> VortexResult<TraversalOrder>

Walk the node’s children by applying f to them.

fn map_children<F: FnMut(Self) -> VortexResult<Transformed<Self>>>( self, f: F, ) -> VortexResult<Transformed<Self>>

Rewrite the node’s children by applying f to them.

fn iter_children<T>( &self, f: impl FnOnce(&mut dyn Iterator<Item = &Self>) -> T, ) -> T
