type PeekThresholdReader

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

PeekThresholdReader allows a check to see if the size of a given reader exceeds the maximum inline segment size or not.

func NewPeekThresholdReader

func NewPeekThresholdReader(r io.Reader) (pt *PeekThresholdReader)

NewPeekThresholdReader creates a new instance of PeekThresholdReader

func (*PeekThresholdReader) IsLargerThan

func (pt *PeekThresholdReader) IsLargerThan(thresholdSize int) (bool, error)

IsLargerThan returns a bool to determine whether a reader's size is larger than the given threshold or not.

func (*PeekThresholdReader) Read

func (pt *PeekThresholdReader) Read(p []byte) (n int, err error)

Read initially reads bytes from the internal buffer, then continues reading from the wrapped data reader. The number of bytes read `n` is returned.

type Repairer

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

NewSegmentRepairer creates a new instance of SegmentRepairer

func (*Repairer) Repair

func (repairer *Repairer) Repair(ctx context.Context, path storj.Path) (err error)

Repair retrieves an at-risk segment and repairs and stores lost pieces on new nodes

type SizedReader

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

SizedReader allows to check the total number of bytes read so far.

func SizeReader
