Implementations

impl FontFaceDescriptors

pub(crate) fn empty() -> Self

pub(crate) fn new( cx: SafeJSContext, val: HandleValue<'_>, ) -> Result<ConversionResult<FontFaceDescriptors>, ()>

impl FontFaceDescriptors

pub(crate) unsafe fn to_jsobject( &self, cx: *mut JSContext, obj: MutableHandleObject<'_>, )

Trait Implementations

impl Clone for FontFaceDescriptors

fn clone(&self) -> FontFaceDescriptors

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for FontFaceDescriptors

fn default() -> Self

Returns the “default value” for a type.

impl FromJSValConvertible for FontFaceDescriptors

type Config = ()

Optional configurable behaviour switch; use () for no configuration.

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, _option: (), ) -> Result<ConversionResult<FontFaceDescriptors>, ()>

Convert val to type Self. Optional configuration of type T can be passed as the option argument. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

impl MallocSizeOf for FontFaceDescriptors

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 ToJSValConvertible for FontFaceDescriptors

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

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

impl Traceable for FontFaceDescriptors

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

Trace self.
