Trait Implementations

impl CSSFontFeatureValuesMapMethods<DomTypeHolder> for CSSFontFeatureValuesMap

fn Size(&self) -> u32

impl DomObject for CSSFontFeatureValuesMap

type ReflectorType = ()

fn reflector(&self) -> &Reflector<Self::ReflectorType>

Returns the receiver’s reflector.

impl DomObjectIteratorWrap<DomTypeHolder> for CSSFontFeatureValuesMap

const ITER_WRAP: unsafe fn(&mut JSContext, &GlobalScope, Option<HandleObject<'_>>, Box<IterableIterator<DomTypeHolder, Self>>) -> Root<Dom<IterableIterator<DomTypeHolder, Self>>>

impl DomObjectWrap<DomTypeHolder> for CSSFontFeatureValuesMap

const WRAP: unsafe fn(&mut JSContext, &GlobalScope, Option<HandleObject<'_>>, Box<Self>) -> Root<Dom<Self>>

Function pointer to the general wrap function type

impl Drop for CSSFontFeatureValuesMap

fn drop(&mut self)

Executes the destructor for this type.

impl HasParent for CSSFontFeatureValuesMap

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 CSSFontFeatureValuesMap

const PROTO_FIRST: u16 = 24

First prototype ID in the DFS-ordered range for this interface and its descendants.

const PROTO_LAST: u16 = 24

Last prototype ID in the DFS-ordered range for this interface and its descendants.

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

Returns whether the given DOM class derives that interface.

impl IteratorDerives for CSSFontFeatureValuesMap

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

impl MallocSizeOf for CSSFontFeatureValuesMap

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 Maplike for CSSFontFeatureValuesMap

type Key = DOMString

The type of the key of the map.

type Value = Vec<u32>

The type of the value of the map.

fn get_index( &self, cx: &mut JSContext, index: u32, ) -> Option<(Self::Key, Self::Value)>

fn get(&self, cx: &mut JSContext, key: Self::Key) -> Option<Self::Value>

fn size(&self, cx: &mut JSContext) -> u32

fn set(&self, cx: &mut JSContext, key: Self::Key, value: Self::Value)

fn has(&self, cx: &mut JSContext, key: Self::Key) -> bool

fn clear(&self, cx: &mut JSContext)

fn delete(&self, cx: &mut JSContext, key: Self::Key) -> bool

impl MutDomObject for CSSFontFeatureValuesMap

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

Initializes the Reflector

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

Initializes the Reflector without recording any associated memory usage.

impl PartialEq for CSSFontFeatureValuesMap

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

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

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

fn safe_to_jsval(&self, cx: &mut JSContext, rval: MutableHandle<'_, Value>)

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

impl Traceable for CSSFontFeatureValuesMap

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

Trace self.
