Struct script::dom::cssrule::CSSRule

#[repr(C)]
pub struct CSSRule {
    reflector_: Reflector,
    parent_stylesheet: Dom<CSSStyleSheet>,
    parent_stylesheet_removed: Cell<bool>,
}

Fields

reflector_: Reflector

parent_stylesheet: Dom<CSSStyleSheet>

parent_stylesheet_removed: Cell<bool>

Whether the parentStyleSheet attribute should return null. We keep parent_stylesheet in that case because insertRule needs it for the stylesheet’s base URL and namespace prefixes.

Implementations

impl CSSRule

pub fn type_id(&self) -> &'static CSSRuleTypeId

impl CSSRule

pub fn new_inherited(parent_stylesheet: &CSSStyleSheet) -> CSSRule

pub fn as_specific(&self) -> &dyn SpecificCSSRule

pub fn new_specific( window: &Window, parent_stylesheet: &CSSStyleSheet, rule: StyleCssRule, ) -> Root<Dom<CSSRule>>

pub fn detach(&self)

Sets owner sheet/rule to null

pub fn deparent(&self)

Sets owner sheet to null (and does the same for all children)

pub fn parent_stylesheet(&self) -> &CSSStyleSheet

pub fn shared_lock(&self) -> &SharedRwLock

Trait Implementations

impl CSSRuleMethods for CSSRule

fn Type(&self) -> u16

fn GetParentStyleSheet(&self) -> Option<Root<Dom<CSSStyleSheet>>>

fn CssText(&self) -> DOMString

fn SetCssText(&self, _: DOMString)

impl Castable for CSSRule

fn is<T>(&self) -> bool

where T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.

fn upcast<T>(&self) -> &T

where T: Castable, Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.

fn downcast<T>(&self) -> Option<&T>

where T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.

impl DomObject for CSSRule

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>

where Self: Sized,

Returns the global scope of the realm that the DomObject was created in.

impl HasParent for CSSRule

fn as_parent(&self) -> &Reflector

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Reflector

impl IDLInterface for CSSRule

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for CSSRule

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 MutDomObject for CSSRule

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq for CSSRule

fn eq(&self, other: &Self) -> 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 ToJSValConvertible for CSSRule

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl Traceable for CSSRule

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
