Implementations

impl UnderlyingSource

pub fn empty() -> Self

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

impl UnderlyingSource

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

Trait Implementations

impl Default for UnderlyingSource

fn default() -> Self

Returns the “default value” for a type.

impl FromJSValConvertible for UnderlyingSource

type Config = ()

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

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

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 ToJSValConvertible for UnderlyingSource

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

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

impl Traceable for UnderlyingSource

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

Trace self.
