us by our associated lock type.

void Update (const T & src)

Defined at line 39 of file ../../zircon/system/ulib/concurrent/include/lib/concurrent/seqlock_payload.h

T & BeginInPlaceUpdate ()

Gain R/W access to the payload in order to perform an in-place update of

the contents fence-to-fence synchronization to protect the payload. All

stores to the payload accessed via this reference should be done using

relaxed atomic stores.
