Function js::jsapi::SetEnqueuePromiseJobCallback [−] [src]

pub unsafe extern "C" fn SetEnqueuePromiseJobCallback(
    rt: *mut JSRuntime, 
    callback: JSEnqueuePromiseJobCallback, 
    data: *mut c_void
)

Sets the callback that's invoked whenever a Promise job should be enqeued.

SpiderMonkey doesn't schedule Promise resolution jobs itself; instead, using this function the embedding can provide a callback to do that scheduling. The provided callback is invoked with the promise job, the corresponding Promise's allocation stack, and the data pointer passed here as arguments.
