Struct layout_2013::display_list::StackingContextId

pub struct StackingContextId(pub u64);

A unique ID for every stacking context.

Tuple Fields

0: u64

The identifier for this StackingContext, derived from the Flow’s memory address and fragment type. As a space optimization, these are combined into a single word.

Implementations

impl StackingContextId

pub fn root() -> StackingContextId

Returns the stacking context ID for the outer document/layout root.

pub fn next(&self) -> StackingContextId

Trait Implementations

impl Clone for StackingContextId

fn clone(&self) -> StackingContextId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackingContextId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StackingContextId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for StackingContextId

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 MallocSizeOf for StackingContextId

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for StackingContextId

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for StackingContextId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StackingContextId
