}示例3: lookupCache
func lookupCache(ctx context.Context, key datastore.Key) *MaybeError {
maybeItem, err := memcache.Get(ctx, key.String())
var result = new(MaybeError)
if err != nil { // treat all errors as "cache miss"
*result = CacheMiss{}
} else {
result = jsonToTodoItem(maybeItem.Value)
}
return result
}示例4: invalidateCache
func invalidateCache(ctx context.Context, key datastore.Key) *MaybeError {
// delete key from memcache
err := memcache.Delete(ctx, key.String())
var result = new(MaybeError)
if err != nil {
*result = E(err.Error())
} else {

case Blob:
blob := ([]byte)((*result).(Blob))
item := memcache.Item{
Key: key.String(),
Value: blob,
}
memcache.Set(ctx, &item) // ignore errors... worst that can happen is we get a cache miss later
default:
break
