Trait moore_vhdl::hir::LatentNode

pub trait LatentNode<'t, T: 't + ?Sized>: Debug {
    fn poll(&self) -> Result<&'t T>;
    fn accept(&self, visitor: &mut dyn Visitor<'t>);
    fn walk(&self, visitor: &mut dyn Visitor<'t>);
}

Lazily resolve to a Node.

Required methods

fn poll(&self) -> Result<&'t T>

Access the underlying node.

On the first time this function is called, the node is created. Subsequent calls are guaranteed to return the same node. Node creation may fail for a variety of reasons, thus the function returns a Result.

fn accept(&self, visitor: &mut dyn Visitor<'t>)

Accept a visitor.

Polls the latent node and if successful calls accept() on it.

fn walk(&self, visitor: &mut dyn Visitor<'t>)

Walk a visitor over the latent node’s subtree.

Polls the latent node and if successful calls walk() on it.
