Struct webrender_api::display_item::SpatialTreeItemKey

#[repr(C)]
pub struct SpatialTreeItemKey {
    key0: u64,
    key1: u64,
}

Defines a caller provided key that is unique for a given spatial node, and is stable across display lists. WR uses this to determine which spatial nodes are added / removed for a new display list. The content itself is arbitrary and opaque to WR, the only thing that matters is that it’s unique and stable between display lists.

Fields

key0: u64

key1: u64

Implementations

impl SpatialTreeItemKey

pub fn new(key0: u64, key1: u64) -> Self

Trait Implementations

impl Clone for SpatialTreeItemKey

fn clone(&self) -> SpatialTreeItemKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpatialTreeItemKey

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

Formats the value using the given formatter.

impl Default for SpatialTreeItemKey

fn default() -> SpatialTreeItemKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SpatialTreeItemKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SpatialTreeItemKey

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 SpatialTreeItemKey

fn eq(&self, other: &SpatialTreeItemKey) -> 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 Peek for SpatialTreeItemKey

unsafe fn peek_from(bytes: *const u8, output: *mut Self) -> *const u8

Deserialize from the buffer pointed to by bytes.

impl Poke for SpatialTreeItemKey

fn max_size() -> usize

Return the maximum number of bytes that the serialized version of Self will occupy.

unsafe fn poke_into(&self, bytes: *mut u8) -> *mut u8

Serialize into the buffer pointed to by bytes.

impl Serialize for SpatialTreeItemKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
