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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
