Functions

func NewTestBucket

func NewTestBucket(t testing.TB) (objstore.Bucket, func(), error)

NewTestBucket creates test bkt client that before returning creates temporary bucket. In a close function it empties and deletes the bucket.

Types

type Bucket

type Bucket struct {
	// contains filtered or unexported fields
}

Bucket implements the store.Bucket interface against cos-compatible(Tencent Object Storage) APIs.

func NewBucket

func NewBucket(logger log.Logger, conf []byte, component string) (*Bucket, error)

NewBucket returns a new Bucket using the provided cos configuration.

func (*Bucket) Close

func (b *Bucket) Close() error

func (*Bucket) Delete

func (b *Bucket) Delete(ctx context.Context, name string) error

Delete removes the object with the given name.

func (*Bucket) Exists

func (b *Bucket) Exists(ctx context.Context, name string) (bool, error)

Exists checks if the given object exists in the bucket.

func (*Bucket) Get

func (b *Bucket) Get(ctx context.Context, name string) (io.ReadCloser, error)

Get returns a reader for the given object name.

func (*Bucket) GetRange

func (b *Bucket) GetRange(ctx context.Context, name string, off, length int64) (io.ReadCloser, error)

GetRange returns a new range reader for the given object name and range.

func (*Bucket) IsObjNotFoundErr

func (b *Bucket) IsObjNotFoundErr(err error) bool

IsObjNotFoundErr returns true if error means that object is not found. Relevant to Get operations.

func (*Bucket) Iter

func (b *Bucket) Iter(ctx context.Context, dir string, f func(string) error) error

Iter calls f for each entry in the given directory (not recursive.). The argument to f is the full object name including the prefix of the inspected directory.

func (*Bucket) Name

func (b *Bucket) Name() string

Name returns the bucket name for COS.

func (*Bucket) ObjectSize

func (b *Bucket) ObjectSize(ctx context.Context, name string) (uint64, error)

ObjectSize returns the size of the specified object.

func (*Bucket) Upload

func (b *Bucket) Upload(ctx context.Context, name string, r io.Reader) error

Upload the contents of the reader as an object into the bucket.

type Config

type Config struct {
	Bucket    string `yaml:"bucket"`
	Region    string `yaml:"region"`
	AppId     string `yaml:"app_id"`
	SecretKey string `yaml:"secret_key"`
	SecretId  string `yaml:"secret_id"`
}

Config encapsulates the necessary config values to instantiate an cos client.
