示例1: GetLog
func GetLog(e storage.Tx, domain, name string) (*Log, error) {
var (
bytes []byte
err error
key string
)
key = fmt.Sprintf(logKey, name)
if bytes, err = e.Get(domain, key); err != nil {
return nil, err
}
if bytes == nil {
return nil, nil
}
log := Log{
Domain: domain,
Name: name,
}
if err = unmarshalLog(bytes, &log); err != nil {
return nil, err
}
return &log, nil
}示例2: GetSegment
// GetSegment returns a segment from storage.
func GetSegment(e storage.Tx, domain string, id *uuid.UUID) (*Segment, error) {
var (
bytes []byte
err error
key string
)
key = fmt.Sprintf(segmentKey, id)
if bytes, err = e.Get(domain, key); err != nil {
return nil, err
}
if bytes == nil {
return nil, nil
}
seg := Segment{
UUID: id,
Domain: domain,
}
if err = unmarshalSegment(bytes, &seg); err != nil {
return nil, err
}
return &seg, nil
}示例3: GetBlock
// GetBlock returns a block from storage. The lookup requires the domain, ID of the segment
// the block is contained in, the index of the block in the segment, and the transaction
// that processed the segment.
func GetBlock(e storage.Tx, domain string, id *uuid.UUID, idx int) ([]byte, error) {
var key string
key = fmt.Sprintf(blockKey, id, idx)
return e.Get(domain, key)
}
