Variables

var ErrNotFound = errors.New("not found")

ErrNotFound means that requested object is not found.

Types

type PDVMeta

type PDVMeta struct {
	// ObjectTypes represents how much certain meta data meta contains.
	ObjectTypes map[schema.Type]uint16 `json:"object_types"`
	Reward      uint64                 `json:"reward"`
}

PDVMeta contains info about PDV.

type Profile

type Profile struct {
	Address   string
	FirstName string
	LastName  string
	Emails    []string
	Bio       string
	Avatar    string
	Gender    string
	Birthday  time.Time
	UpdatedAt *time.Time
	CreatedAt time.Time
}

Profile ...

type RewardMap

type RewardMap map[schema.Type]uint64

RewardMap contains dictionary with PDV types and rewards for them.

type Service

type Service interface {
	// SavePDV sends PDV to storage.
	SavePDV(ctx context.Context, p schema.PDV, owner sdk.AccAddress) (uint64, PDVMeta, error)
	// ListPDV lists PDVs.
	ListPDV(ctx context.Context, owner string, from uint64, limit uint16) ([]uint64, error)
	// ReceivePDV returns slice of bytes of PDV requested by address from storage.
	ReceivePDV(ctx context.Context, owner string, id uint64) ([]byte, error)
	// GetPDVMeta returns PDVs meta.
	GetPDVMeta(ctx context.Context, owner string, id uint64) (PDVMeta, error)

	// GetProfile ...
	GetProfiles(ctx context.Context, owner []string) ([]*Profile, error)

	// GetRewardsMap ...
	GetRewardsMap() RewardMap
}

Service interface provides service's logic's methods.

func New

func New(
	c crypto.Crypto,
	fs storage.FileStorage,
	is storage.IndexStorage,
	b blockchain.Blockchain,
	rewardMap RewardMap,
) Service

New returns new instance of service.
