Overview

Package clientutils provides utility functions for the storage client & client FSM

Index

• func CommP(ctx context.Context, pieceIO pieceio.PieceIO, rt abi.RegisteredSealProof, ...) (cid.Cid, abi.UnpaddedPieceSize, error)
• func LabelField(payloadCID cid.Cid) ([]byte, error)
• func VerifyResponse(ctx context.Context, resp network.SignedResponse, minerAddr address.Address, ...) error
• type VerifyFunc

Functions

func CommP

func CommP(ctx context.Context, pieceIO pieceio.PieceIO, rt abi.RegisteredSealProof, data *storagemarket.DataRef, storeID *multistore.StoreID) (cid.Cid, abi.UnpaddedPieceSize, error)

CommP calculates the commP for a given dataref

func LabelField

func LabelField(payloadCID cid.Cid) ([]byte, error)

LabelField makes a label field for a deal proposal as a CBOR encoded struct with the following structure:

{
	 "pcids": [payloadCID]
}

func VerifyResponse

func VerifyResponse(ctx context.Context, resp network.SignedResponse, minerAddr address.Address, tok shared.TipSetToken, verifier VerifyFunc) error

VerifyResponse verifies the signature on the given signed response matches the given miner address, using the given signature verification function

Types

type VerifyFunc

type VerifyFunc func(context.Context, crypto.Signature, address.Address, []byte, shared.TipSetToken) (bool, error)

VerifyFunc is a function that can validate a signature for a given address and bytes
