Defined at line 40 of file ../../src/lib/fxl/memory/weak_ptr.h

Class for "weak pointers" that can be invalidated. Valid weak pointers can

only originate from a |WeakPtrFactory| (see below), though weak pointers are

copyable and movable.

Weak pointers are not in general thread-safe. They may only be *used* on a

single thread, namely the same thread as the "originating" |WeakPtrFactory|

(which can invalidate the weak pointers that it generates).

However, weak pointers may be passed to other threads, reset on other

threads, or destroyed on other threads. They may also be reassigned on other

threads (in which case they should then only be used on the thread

corresponding to the new "originating" |WeakPtrFactory|).
