Type Alias mozjs::jsapi::WriteStructuredCloneOp

pub type WriteStructuredCloneOp = Option<unsafe extern "C" fn(_: *mut JSContext, _: *mut JSStructuredCloneWriter, _: Handle<*mut JSObject>, _: *mut bool, _: *mut c_void) -> bool>;

Structured data serialization hook. The engine can write primitive values, Objects, Arrays, Dates, RegExps, TypedArrays, ArrayBuffers, Sets, Maps, and SharedTypedArrays. Any other type of object requires application support. This callback must first use the JS_WriteUint32Pair API to write an object header, passing a value greater than JS_SCTAG_USER to the tag parameter. Then it can use the JS_Write* APIs to write any other relevant parts of the value v to the writer w. closure is any value passed to the JS_WriteStructuredClone function.

Return true on success, false on error. On error, an exception should normally be set.

Aliased Type

enum WriteStructuredCloneOp {
    None,
    Some(unsafe extern "C" fn(_: *mut JSContext, _: *mut JSStructuredCloneWriter, _: Handle<*mut JSObject>, _: *mut bool, _: *mut c_void) -> bool),
}

Variants

None

No value.

Some(unsafe extern "C" fn(_: *mut JSContext, _: *mut JSStructuredCloneWriter, _: Handle<*mut JSObject>, _: *mut bool, _: *mut c_void) -> bool)

Some value of type T.

Trait Implementations

impl<T: CustomTrace> CustomTrace for Option<T>

fn trace(&self, trc: *mut JSTracer)

impl<T: FromJSValConvertible> FromJSValConvertible for Option<T>

type Config = <T as FromJSValConvertible>::Config

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

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, option: T::Config ) -> Result<ConversionResult<Option<T>>, ()>

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<T: ToJSValConvertible> ToJSValConvertible for Option<T>

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

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

impl<T: Traceable> Traceable for Option<T>

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

Trace self.
