Trait NodeWithMetadata 

pub trait NodeWithMetadata<M: NodeMetadata> {
    // Required method
    fn metadata(&self) -> M;

    // Provided method
    fn self_metadata(&self) -> M { ... }
}

A Node that has NodeMetadata

Required Methods

fn metadata(&self) -> M

Returns the complete aggregated metadata for this node (self + children). Default implementation merges children’s metadata with self_metadata().

Provided Methods

fn self_metadata(&self) -> M

Returns the metadata contributed by this node itself, not including children. Most nodes don’t contribute metadata, so can simply return M::default(). Nodes like StyleRule or AtRules should return their own node kind flags here.
