type QuerySchema ¶ added in v0.4.1

type QuerySchema struct {
	// contains filtered or unexported fields
}

QuerySchema is really overkill for this example, but it's here for demo purposes It provides a Prefixed wrapper to a snapshot of the state store

func NewQuerySchema ¶ added in v0.4.1

func NewQuerySchema(store sdk.Snapshot) QuerySchema

func (QuerySchema) GetCountByKey ¶ added in v0.4.1

func (qs QuerySchema) GetCountByKey(k []byte) sdk.Result

type Schema ¶

type Schema struct {
	// contains filtered or unexported fields
}

Schema wraps a prefixed store for our service

func NewSchema ¶

func NewSchema(store sdk.Cache) Schema

func (Schema) IncrementCount ¶

func (schema Schema) IncrementCount(sender []byte, msg Increment) sdk.Result

IncrementCount is the core logic for a tx

type Service ¶

type Service struct{}

Service is a simple service to demonstrate the menta API. It stores a counter for each tx.sender

func (Service) Execute ¶

func (srv Service) Execute(sender []byte, msgid uint32, message []byte, store sdk.Cache) sdk.Result

Execute runs the core logic for a state transition

func (Service) Initialize ¶

func (srv Service) Initialize(data []byte, store sdk.Cache)

Initialize is called on the genesis block. Not used

func (Service) Name ¶

func (srv Service) Name() string

Name is a unique name used to register the service

func (srv Service) Query(key []byte, store sdk.Snapshot) sdk.Result

Query committed state for the given used. Key is the public key bytes

type Wallet ¶

type Wallet struct {
	// contains filtered or unexported fields
}

func CreateWallet ¶

func CreateWallet() Wallet

func WalletFromSeed ¶

func WalletFromSeed(seed string) Wallet
