func TestSharedMemoryLargeBatchSize

func TestSharedMemoryLargeBatchSize(t *testing.T, _, chainID1 ids.ID, sm0, _ SharedMemory, db database.Database)

TestSharedMemoryLargeBatchSize tests to make sure that the interface can support large batches.

func TestSharedMemoryLargeIndexed

func TestSharedMemoryLargeIndexed(t *testing.T, chainID0, chainID1 ids.ID, sm0, sm1 SharedMemory, _ database.Database)

func TestSharedMemoryLargePutGetAndRemove

func TestSharedMemoryLargePutGetAndRemove(t *testing.T, chainID0, chainID1 ids.ID, sm0, sm1 SharedMemory, _ database.Database)

TestSharedMemoryLargePutGetAndRemove tests to make sure that the interface can support large values.

func TestSharedMemoryPutAndGet

func TestSharedMemoryPutAndGet(t *testing.T, chainID0, chainID1 ids.ID, sm0, sm1 SharedMemory, _ database.Database)

func WriteAll

func WriteAll(baseBatch database.Batch, batches ...database.Batch) error

WriteAll assumes all batches have the same underlying database. Batches should not be modified after being passed to this function.

Types
