Trait Implementations

impl Biplate<Literal> for Atom

Definition of a Biplate.

fn with_children_bi(&self, children: VecDeque<To>) -> Self

Reconstructs the node with the given children.

Applies the given function to all nodes bottom up.

fn holes_bi(&self) -> impl Iterator<Item = (To, Arc<dyn Fn(To) -> Self>)>
