Functions ¶

func SeqAtomicStore ¶

func SeqAtomicStore(seq *sync.SeqCount, ptr *Value, val Value)

SeqAtomicStore sets *ptr to a copy of val, ensuring that any racing reader critical sections are forced to retry.

func SeqAtomicStoreSeqed ¶

func SeqAtomicStoreSeqed(ptr *Value, val Value)

SeqAtomicStoreSeqed sets *ptr to a copy of val.

Preconditions: ptr is protected by a SeqCount that will be in a writer critical section throughout the call to SeqAtomicStore.

Types ¶

type Value ¶

type Value struct{}

Value is a required type parameter.

func SeqAtomicLoad ¶

func SeqAtomicLoad(seq *sync.SeqCount, ptr *Value) Value

SeqAtomicLoad returns a copy of *ptr, ensuring that the read does not race with any writer critical sections in seq.

func SeqAtomicTryLoad ¶

func SeqAtomicTryLoad(seq *sync.SeqCount, epoch sync.SeqCountEpoch, ptr *Value) (val Value, ok bool)

SeqAtomicTryLoad returns a copy of *ptr while in a reader critical section in seq initiated by a call to seq.BeginRead() that returned epoch. If the read would race with a writer critical section, SeqAtomicTryLoad returns (unspecified, false).
