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 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. 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
}

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) Approve

func (c *VaccinationContract) Approve(ctx contractapi.TransactionContextInterface, operator string, tokenId string) (bool, error)

func (*VaccinationContract) BalanceOf

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

func (*VaccinationContract) ClientAccountId

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

func (*VaccinationContract) SetApprovalForAll

func (c *VaccinationContract) SetApprovalForAll(ctx contractapi.TransactionContextInterface, operator string, approved bool) (bool, error)

func (*VaccinationContract) TransferFrom

func (c *VaccinationContract) TransferFrom(ctx contractapi.TransactionContextInterface, from string, to string, tokenId string) (bool, 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"`
}

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
