adapters

Documentation

Overview

Package adapters contains the private glue that composes the per-service packages (warmstorage, spregistry, payments, costs, internal/contracts/ pdpverifier) into the narrow interfaces consumed by the storage package.

This package is a root-synapse implementation detail. It must not be imported outside the SDK and must not import the root synapse package. Each exported constructor returns a storage-package interface so that the concrete adapter types stay unexported and never enlarge the public API.

Functions

func NewCostCalculator

func NewCostCalculator(c *costs.Service) storage.MultiCostCalculator

NewCostCalculator returns a storage.MultiCostCalculator backed by c.

func NewDataSetFinder

func NewDataSetFinder(ws *warmstorage.Service) storage.DataSetFinder

NewDataSetFinder returns a storage.DataSetFinder backed by ws.

func NewPaymentsFunder

func NewPaymentsFunder(p *payments.Service) storage.PaymentsFunder

NewPaymentsFunder returns a storage.PaymentsFunder backed by p.

func NewStorageInfoReader

func NewStorageInfoReader(ws *warmstorage.Service, sp *spregistry.Service, pay *payments.Service, usdfcToken, fwss common.Address) storage.StorageInfoReader

NewStorageInfoReader returns a storage.StorageInfoReader that assembles pricing, providers and allowances from ws, sp and pay.

Types

type PDPReader

type PDPReader interface {
	storage.PDPVerifierReader
	storage.DataSetSizeReader
}

PDPReader is the union of storage.PDPVerifierReader and storage.DataSetSizeReader satisfied by a single adapter around the abigen PDPVerifierCaller plus an ethclient. Root synapse holds a single field of this type and fans it out to both storage options.

func NewPDPVerifierReader

func NewPDPVerifierReader(caller *pdpverifier.PDPVerifierCaller, backend *ethclient.Client) PDPReader

NewPDPVerifierReader returns a PDPReader wrapping caller and backend. When caller is nil it returns a nil interface value, letting callers keep the plain `if r != nil` check without hitting Go's typed-nil interface trap.
