🔬This is a nightly-only experimental API. (thread_local_internals)
pub unsafe fn get(&self) -> *const T
thread_local_internals)Gets a pointer to the TLS value. If the TLS variable has been destroyed, a null pointer is returned.
The resulting pointer may not be used after thread destruction has occurred.
§Safety
The self reference must remain valid until the TLS destructor is run.
