pub struct CustomAutoRooterGuard<'a, T>
where T: 'a + CustomTrace,
{ rooter: &'a mut CustomAutoRooter<T>, }
Expand description

An RAII guard used to root underlying data in CustomAutoRooter until the guard is dropped (falls out of scope). The underlying data can be accessed through this guard via its Deref and DerefMut implementations. This structure is created by root method on CustomAutoRooter or by the auto_root! macro.
