Type Alias mozjs::jsapi::JS::BuildIdOp

pub type BuildIdOp = Option<unsafe extern "C" fn(_: *mut u8) -> bool>;

Return the buildId (represented as a sequence of characters) associated with the currently-executing build. If the JS engine is embedded such that a single cache entry can be observed by different compiled versions of the JS engine, it is critical that the buildId shall change for each new build of the JS engine.

Aliased Type

enum BuildIdOp {
    None,
    Some(unsafe extern "C" fn(_: *mut u8) -> bool),
}

Variants

None

No value.

Some(unsafe extern "C" fn(_: *mut u8) -> 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.
