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.
A vector of items to be rooted with RootedVec.
Guaranteed to be empty when not rooted.
Rust API for keeping a Rooted value in the context’s root stack.
Example usage: rooted!(in(cx) let x = UndefinedValue());.
RootedGuard::new also works, but the macro is preferred.
Roots any JSTraceable thing
Holds a set of JSTraceables that need to be rooted
A vector of items rooted for the lifetime ’a.
