class WeakInspector
Defined at line 116 of file ../../zircon/system/ulib/inspect/include/lib/inspect/cpp/inspector.h
A weak handle to an Inspector.
Can be safely captured by value in lazy node callbacks.
Using WeakInspector avoids:
1. Reference cycles: Capturing a strong Inspector by value in a callback owned
by that Inspector creates a cycle, preventing destruction.
2. Dangling pointers: Capturing a strong Inspector by reference (or raw pointer)
is unsafe because Inspector is copyable. The original Inspector instance
might be destroyed while a copy keeps the underlying state (and the callback)
alive.
Public Methods
Inspector lock ()Attempts to promote this weak handle to a strong Inspector handle.
Returns a full-fledged copy of the original Inspector if all internal shared
objects are still alive, or a no-op Inspector (which evaluates to false in
boolean contexts) if the original Inspector was destroyed.
