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.

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)

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

Iter calls f for each entry in the given directory. The argument to f is the full object name including the prefix of the inspected directory.

func (*Bucket) Name added in v0.2.0

func (b *Bucket) Name() string

Name returns the bucket name for s3.

func (*Bucket) Upload
