Types

type Decl 

type Decl struct {
	abi.SectorID
	storiface.SectorFileType
}

type DefaultPartialFileHandler added in v1.11.0 

type DefaultPartialFileHandler struct{}

DefaultPartialFileHandler is the default implementation of the partialFileHandler interface. This is probably the only implementation we'll ever use because the purpose of the interface to is to mock out partial file related functionality during testing.

func (*DefaultPartialFileHandler) Close added in v1.11.0 

func (d *DefaultPartialFileHandler) Close(pf *partialfile.PartialFile) error

Close closes the partial file

func (*DefaultPartialFileHandler) HasAllocated added in v1.11.0

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.
