Types

type Code 

type Code struct {
	CodeInfo   CodeInfo `json:"code_info"`
	CodesBytes []byte   `json:"code_bytes"`
}

Code struct encompasses CodeInfo and CodeBytes

type CodeInfo 

type CodeInfo struct {
	CodeHash []byte         `json:"code_hash"`
	Creator  sdk.AccAddress `json:"creator"`
	Source   string         `json:"source"`
	Builder  string         `json:"builder"`
}

CodeInfo is data for the uploaded contract WASM code

func NewCodeInfo 

func NewCodeInfo(codeHash []byte, creator sdk.AccAddress, source string, builder string) CodeInfo

NewCodeInfo fills a new Contract struct

type Contract 

type Contract struct {
	ContractAddress sdk.AccAddress `json:"contract_address"`
	ContractInfo    ContractInfo   `json:"contract_info"`
	ContractState   []Model        `json:"contract_state"`
}

Contract struct encompasses ContractAddress, ContractInfo, and ContractState

type ContractInfo 

type ContractInfo struct {
	CodeID  uint64          `json:"code_id"`
	Creator sdk.AccAddress  `json:"creator"`
	Label   string          `json:"label"`
	InitMsg json.RawMessage `json:"init_msg,omitempty"`
	// never show this in query results, just use for sorting
	// (Note: when using json tag "-" amino refused to serialize it...)
	Created *CreatedAt `json:"created,omitempty"`
}

ContractInfo stores a WASM contract instance

func NewContractInfo 

func NewContractInfo(codeID uint64, creator sdk.AccAddress, initMsg []byte, label string, createdAt *CreatedAt) ContractInfo

NewContractInfo creates a new instance of a given WASM contract info

type CreatedAt 

type CreatedAt struct {
	// BlockHeight is the block the contract was created at
	BlockHeight int64
	// TxIndex is a monotonic counter within the block (actual transaction index, or gas consumed)
	TxIndex uint64
}

CreatedAt can be used to sort contracts

func NewCreatedAt 

func NewCreatedAt(ctx sdk.Context) *CreatedAt

NewCreatedAt gets a timestamp from the context

func (*CreatedAt) LessThan 

func (a *CreatedAt) LessThan(b *CreatedAt) bool

LessThan can be used to sort
