示例1: Put
func (ds *S3Datastore) Put(key datastore.Key, value interface{}) (err error) {
data, ok := value.([]byte)
if !ok {
return ErrInvalidType
}
// TODO extract perms and s3 options
return ds.Client.Bucket(ds.Bucket).Put(key.String(), data, "application/protobuf", s3.PublicRead, s3.Options{})

}示例3: PrefixTransform
// PrefixTransform constructs a KeyTransform with a pair of functions that
// add or remove the given prefix key.
//
// Warning: will panic if prefix not found when it should be there. This is
// to avoid insidious data inconsistency errors.
func PrefixTransform(prefix ds.Key) ktds.KeyTransform {
return &ktds.Pair{
// Convert adds the prefix
Convert: func(k ds.Key) ds.Key {
return prefix.Child(k)
},
// Invert removes the prefix. panics if prefix not found.
Invert: func(k ds.Key) ds.Key {

panic("expected prefix not found")
}
s := strings.TrimPrefix(k.String(), prefix.String())
return ds.NewKey(s)
},
}

}
}

return ds.Client.Bucket(ds.Bucket).Get(key.String())
}示例8: KeyFromDsKey
// KeyFromDsKey returns a Datastore key
func KeyFromDsKey(dsk ds.Key) Key {
return Key(dsk.String()[1:])
}示例9: Delete
func (ds *Datastore) Delete(key datastore.Key) (err error) {
ds.mu.Lock()
defer ds.mu.Unlock()
return ds.client.Cmd("DEL", key.String()).Err
}示例10: Has
func (ds *Datastore) Has(key datastore.Key) (exists bool, err error) {
ds.mu.Lock()
