Implementations

impl CSSRuleList

pub fn new_inherited(
    parent_stylesheet: &CSSStyleSheet,
    rules: RulesSource
) -> CSSRuleList

pub fn new(
    window: &Window,
    parent_stylesheet: &CSSStyleSheet,
    rules: RulesSource
) -> Root<Dom<CSSRuleList>>

pub fn insert_rule(&self, rule: &str, idx: u32, nested: bool) -> Result<u32, Error>

Should only be called for CssRules-backed rules. Use append_lazy_rule for keyframes-backed rules.

pub fn remove_rule(&self, index: u32) -> Result<(), Error>

pub fn deparent_all(&self)

pub fn item(&self, idx: u32) -> Option<Root<Dom<CSSRule>>>

pub fn append_lazy_dom_rule(&self)

Add a rule to the list of DOM rules. This list is lazy, so we just append a placeholder.

Should only be called for keyframes-backed rules, use insert_rule for CssRules-backed rules

Trait Implementations

impl CSSRuleListMethods for CSSRuleList

fn Item(&self, idx: u32) -> Option<Root<Dom<CSSRule>>>

fn Length(&self) -> u32

fn IndexedGetter(&self, index: u32) -> Option<Root<Dom<CSSRule>>>

impl DomObject for CSSRuleList

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 DomObjectWrap for CSSRuleList

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::CSSRuleListBinding::CSSRuleListBinding::Wrap as for<'a> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::boxed::Box<dom::cssrulelist::CSSRuleList>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::cssrulelist::CSSRuleList>>}

Function pointer to the general wrap function type

impl HasParent for CSSRuleList

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 CSSRuleList

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

Returns whether the given DOM class derives that interface.

impl JSTraceable for CSSRuleList

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

Trace self.

impl MallocSizeOf for CSSRuleList

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 CSSRuleList

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

Initializes the Reflector

impl PartialEq<CSSRuleList> for CSSRuleList

fn eq(&self, other: &CSSRuleList) -> 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 CSSRuleList

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

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