Takes an owning pointer to TTarget* and creates an intrusive_ptr
representing a new reference, i.e.
|
static BackendMetaRef |
reclaim(BackendMeta owning_ptr)
Takes an owning pointer to TTarget* and creates an intrusive_ptr that takes
over ownership.
|
BackendMeta |
release()
Returns an owning (!) pointer to the underlying object and makes the
intrusive_ptr instance invalid.

unsafe_adapt_non_heap_allocated(BackendMeta raw_ptr,
long expected_decrefs)
Turn an instance of TTarget that should not be reference counted
(e.g., allocated into an arena with placement new) into an
intrusive_ptr.
|
static BackendMetaRef |
unsafe_reclaim_from_nonowning(BackendMeta raw_ptr)
Turn a **non-owning raw pointer** to an intrusive_ptr.
|
static BackendMetaRef |
unsafe_steal_from_new(BackendMeta raw_ptr)
Turn a new instance of TTarget (e.g., literally allocated
using new TTarget(...) into an intrusive_ptr.

expected_decrefs
is a debugging parameter: it indicates the
number of strong owners the intrusive_ptr_target in question is
expected to get. In most use cases, this will likely be 1.
The reason this method exists is for manually sharing
StorageImpls across Tensors in the static runtime. It needs
access to private intrusive_ptr members so that the refcounts can
be initialized to custom values.@ByVal public static BackendMetaRef unsafe_reclaim_from_nonowning(BackendMeta raw_ptr)
