Struct mozjs_sys::jsapi::JS::MutableHandle
source · #[repr(C)]pub struct MutableHandle<T> {
pub ptr: *mut T,
pub _phantom_0: PhantomData<UnsafeCell<T>>,
}
Expand description
Similar to a handle, but the underlying storage can be changed. This is useful for outparams.
If you want to add additional methods to MutableHandle for a specific
specialization, define a MutableHandleOperations
