Enum webrender::spatial_node::SpatialNodeUidKind

pub enum SpatialNodeUidKind {
    Root,
    InternalScrollFrame,
    InternalReferenceFrame,
    External {
        key: SpatialTreeItemKey,
    },
}

The kind of a spatial node uid. These are required because we currently create external nodes during DL building, but the internal nodes aren’t created until scene building. TODO(gw): The internal scroll and reference frames are not used in any important way

Variants

Root

The root node of the entire spatial tree

InternalScrollFrame

Internal scroll frame created during scene building for each iframe

InternalReferenceFrame

Internal reference frame created during scene building for each iframe

External

A normal spatial node uid, defined by a caller provided unique key

Fields

key: SpatialTreeItemKey

Trait Implementations

impl Clone for SpatialNodeUidKind

fn clone(&self) -> SpatialNodeUidKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpatialNodeUidKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SpatialNodeUidKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SpatialNodeUidKind

fn eq(&self, other: &SpatialNodeUidKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SpatialNodeUidKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
