Struct kuchiki::NodeDataRef

pub struct NodeDataRef<T> { /* fields omitted */ }

Holds a strong reference to a node, but dereferences to some component inside of it.

Methods

impl<T> NodeDataRef<T>

pub fn new<F>(rc: NodeRef, f: F) -> NodeDataRef<T> where     F: FnOnce(&Node) -> &T,

Create a NodeDataRef for a component in a given node.

pub fn new_opt<F>(rc: NodeRef, f: F) -> Option<NodeDataRef<T>> where     F: FnOnce(&Node) -> Option<&T>,
