Functions

func FetchWithTemp added in v1.17.2 

func FetchWithTemp(ctx context.Context, urls []string, dest string, header http.Header) (string, error)

func (*Remote) CheckIsUnsealed 

func (r *Remote) CheckIsUnsealed(ctx context.Context, s storiface.SectorRef, offset, size abi.PaddedPieceSize) (bool, error)

func (r *Remote) Reader(ctx context.Context, s storiface.SectorRef, offset, size abi.PaddedPieceSize) (func(startOffsetAligned storiface.PaddedByteIndex) (io.ReadCloser, error), error)

Reader returns a reader for an unsealed piece at the given offset in the given sector. If the Miner has the unsealed piece locally, it will return a reader that reads from the local copy. If the Miner does NOT have the unsealed piece locally, it will query all workers that have the unsealed sector file to know if they have the unsealed piece and will then read the unsealed piece data from a worker that has it.

Returns a nil reader if : 1. no worker(local worker included) has an unsealed file for the given sector OR 2. no worker(local worker included) has the unsealed piece in their unsealed sector file. Will return a nil reader and a nil error in such a case.
