Types ¶
type DiskImage ¶
type DiskImage struct {
// contains filtered or unexported fields
}
DiskImage -.
func (*DiskImage) Commit ¶
Commit commits the blob (but no roll-back is guaranteed on an error). size and expected can be zero-value when unknown. Commit always closes the writer, even on error. ErrAlreadyExists aborts the writer.
func (*DiskImage) Digest ¶
func (w *DiskImage) Digest() digest.Digest
Digest may return empty digest or panics until committed.
func (*DiskImage) Status ¶
func (w *DiskImage) Status() (ctrcontent.Status, error)
Status returns the current state of write.
type DiskImageStore ¶
type DiskImageStore struct {
// contains filtered or unexported fields
}
DiskImageStore -.
func NewDiskImageStore ¶
func NewDiskImageStore(sourceImage string, compressed bool, w io.Writer) DiskImageStore
NewDiskImageStore -.
func (DiskImageStore) Writer ¶
func (d DiskImageStore) Writer(_ context.Context, opts ...ctrcontent.WriterOpt) (ctrcontent.Writer, error)
Writer get a writer.
type WriteCounter ¶
type WriteCounter struct {
Total uint64
}
WriteCounter counts the number of bytes written to it. It implements to the io.Writer interface and we can pass this into io.TeeReader() which will report progress on each write cycle.
