Struct NodeId 

pub struct NodeId(/* private fields */);

Identity of one node in the content tree, for diagnostics and incremental relayout.

Assigned in document order, starting at 1.

Implementations

impl NodeId

pub const UNASSIGNED: NodeId

What every node’s id is before assignment.

pub fn get(self) -> u32

The raw id. Monotonic in document order within one book.

pub fn new(id: u32) -> NodeId

The node one number names. Identity stays the engine’s to hand out; this is how a host asks about an id it read off a display structure, and an id no node has answers with nothing.

pub fn pseudo_element(self) -> Option<(NodeId, PseudoElement)>

The element and the pseudo-element this id names, where it names one. Nothing for the id of a content node.

pub fn element(self) -> NodeId

The element this id stands for: the element a pseudo-element belongs to, or the node itself.

Trait Implementations
