Types

type Approval 

type Approval struct {
	Owner    string `json:"owner"`
	Approved string `json:"operator"`
	TokenId  string `json:"tokenId"`
}

type ApprovalForAll 

type ApprovalForAll struct {
	Owner    string `json:"owner"`
	Operator string `json:"operator"`
	Approved bool   `json:"approved"`
}

type TokenIdGenerator added in v1.0.0 

type TokenIdGenerator struct {
}

func (*TokenIdGenerator) HasNext added in v1.0.0 

func (g *TokenIdGenerator) HasNext() bool

func (*TokenIdGenerator) Next added in v1.0.0 

func (g *TokenIdGenerator) Next() string

type TokenIdGeneratorInterface added in v1.0.0 

type TokenIdGeneratorInterface interface {
	HasNext() bool
	Next() string
}

type TradeOffer 

type TradeOffer struct {
	Uuid          string `json:"uuid"`
	Sender        string `json:"sender"`
	SenderItem    string `json:"senderItem"`
	Recipient     string `json:"recipient"`
	RecipientItem string `json:"recipientItem"`
}

TradeOffer represents a trade offer for specific slots of specific identities.

Making an offer: 

func (c *VaccinationContract) MakeOffer(ctx contractapi.TransactionContextInterface, mySlotUuid, recipient, recipientSlotUuid string) (offerUuid string, err error)

Accepting an offer: 

func (c *VaccinationContract) AcceptOffer(ctx contractapi.TransactionContextInterface, offerUuid string) error

Offers are stored in the global state as offer.sender.offerUuid and offer.recipient.offerUuid offer.offerUuid. This way it enables queries by partial key.

type Transfer 

type Transfer struct {
	From    string `json:"from"`
	To      string `json:"to"`
	TokenId string `json:"tokenId"`
}

type VaccinationContract 

type VaccinationContract struct {
	contractapi.Contract
	IdGenerator TokenIdGeneratorInterface
}

VaccinationContract is a smart contract for managing vaccination slots. Implements ERC-721.

func (*VaccinationContract) AcceptOffer 

func (c *VaccinationContract) AcceptOffer(ctx contractapi.TransactionContextInterface, offerUuid string) error

func (*VaccinationContract) BalanceOf 

func (c *VaccinationContract) BalanceOf(ctx contractapi.TransactionContextInterface, owner string) int

func (*VaccinationContract) BurnToken added in v1.0.0 

func (c *VaccinationContract) BurnToken(ctx contractapi.TransactionContextInterface, slotUuid string) error

func (*VaccinationContract) ClientAccountId 

func (c *VaccinationContract) ClientAccountId(ctx contractapi.TransactionContextInterface) (string, error)

func (*VaccinationContract) DeleteOffer added in v1.0.0 

func (c *VaccinationContract) DeleteOffer(ctx contractapi.TransactionContextInterface, offerUuid string) error

func (*VaccinationContract) GetApproved 

func (c *VaccinationContract) GetApproved(ctx contractapi.TransactionContextInterface, tokenId string) (string, error)

func (*VaccinationContract) GetSlots 

func (c *VaccinationContract) GetSlots(ctx contractapi.TransactionContextInterface, owner string) (string, error)

func (*VaccinationContract) IsApprovedForAll 

func (c *VaccinationContract) IsApprovedForAll(ctx contractapi.TransactionContextInterface, owner string, operator string) (bool, error)

func (*VaccinationContract) IssueSlot 

func (c *VaccinationContract) IssueSlot(ctx contractapi.TransactionContextInterface, vaccine, date, patient, previous string) (string, error)

IssueSlot can be used by doctors to issue vaccination slots to patients.

Vaccine must be one of the values defined VaccinationType enum.

Date format must be 2006-01-02.

func (*VaccinationContract) ListOffers added in v0.1.1 

func (c *VaccinationContract) ListOffers(ctx contractapi.TransactionContextInterface) (string, error)

func (*VaccinationContract) MakeOffer 

func (c *VaccinationContract) MakeOffer(ctx contractapi.TransactionContextInterface, mySlotUuid, recipient, recipientSlotUuid string) (offerUuid string, err error)

func (*VaccinationContract) OwnerOf 

func (c *VaccinationContract) OwnerOf(ctx contractapi.TransactionContextInterface, tokenId string) (string, error)

type VaccinationDate 

type VaccinationDate time.Time

VaccinationDate is a simplified date format to identify specific occasions

func (*VaccinationDate) MarshalJSON 

func (vd *VaccinationDate) MarshalJSON() ([]byte, error)

MarshalJSON marshals the date into 2006-01-02 format

func (*VaccinationDate) UnmarshalJSON 

func (vd *VaccinationDate) UnmarshalJSON(b []byte) (err error)

UnmarshalJSON unmarshals date from 2006-01-02 format

type VaccinationSlot 

type VaccinationSlot struct {
	VaccinationSlotData
	TokenId  string `json:"tokenId"`
	Owner    string `json:"owner"`
	Approved string `json:"approved"`
}

VaccinationSlot contains ERC712 related data (this is the NFT)

type VaccinationSlotData 

type VaccinationSlotData struct {
	// Type of the vaccine.
	// May change when the token is transferred.
	Type VaccinationType `json:"type"`

	// When the vaccine should be administered.
	// Never changes.
	Date VaccinationDate `json:"date"`

	// Previously administered vaccine of the same type.
	// If present it may forbid the transfer of the token.
	// May change when the token is transferred.
	Previous string `json:"previous,omitempty"`

	Burned bool `json:"burned,omitempty"`
}

VaccinationSlotData contains information about specific occasion

type VaccinationType 

type VaccinationType string
const (
	Alpha   VaccinationType = "alpha"
	Bravo   VaccinationType = "bravo"
	Charlie VaccinationType = "charlie"
	Delta   VaccinationType = "delta"
	Echo    VaccinationType = "echo"
)

func (*VaccinationType) MarshalJSON 

func (vt *VaccinationType) MarshalJSON() ([]byte, error)

func (*VaccinationType) UnmarshalJSON 

func (vt *VaccinationType) UnmarshalJSON(data []byte) error
