NoGC

mozjs::context

Struct NoGC 

Source 
pub struct NoGC<'cx>(PhantomData<&'cx ()>);
Expand description

Token that ensures that no GC can happen while it is alive.

Each function that trigger GC require mutable access to JSContext, so one cannot call them because NoGC lifetime is bounded to JSContext.

For more info and examples see JSContext.
