Function mozjs::jsapi::StartIncrementalGC

pub unsafe extern "C" fn StartIncrementalGC(
    cx: *mut JSContext,
    options: GCOptions,
    reason: GCReason,
    budget: *const SliceBudget
)

Begin an incremental collection and perform one slice worth of work. When this function returns, the collection may not be complete. IncrementalGCSlice() must be called repeatedly until !IsIncrementalGCInProgress(cx).

Note: SpiderMonkey’s GC is not realtime. Slices in practice may be longer or shorter than the requested interval.
