Enum ContainerAttributeDependencyKind 

#[repr(C)]
pub enum ContainerAttributeDependencyKind {
    None = 0,
    UnnamedContainer = 1,
    NamedContainer = 2,
}

Whether this container uses attr() references and if so whether or not this is a named or unnamed container query. Used for determining which kind of restyle hint we need when traversing invalidation.

Variants

None = 0

This container does not use attr() references.

UnnamedContainer = 1

This unnamed container uses attr() references.

NamedContainer = 2

This named container uses attr() references.

Implementations

impl ContainerAttributeDependencyKind

pub fn element_container_dependency_kind<E: TElement>( element: E, local_name: &LocalName, stylist: &Stylist, ) -> Self

A named container that uses attr needs to invalidate all descendants that are affected by style container queries. If we only have an unnamed container or no attribute dependencies we keep looking for a condition that would require us to invalidate more.

Trait Implementations

impl Clone for ContainerAttributeDependencyKind

fn clone(&self) -> ContainerAttributeDependencyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContainerAttributeDependencyKind

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

Formats the value using the given formatter.

impl MallocSizeOf for ContainerAttributeDependencyKind

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 Ord for ContainerAttributeDependencyKind

fn cmp(&self, other: &ContainerAttributeDependencyKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ContainerAttributeDependencyKind

fn eq(&self, other: &ContainerAttributeDependencyKind) -> 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 PartialOrd for ContainerAttributeDependencyKind

fn partial_cmp( &self, other: &ContainerAttributeDependencyKind, ) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
