Functions

func EncodeTx 

func EncodeTx(tx *SignedTransaction) ([]byte, error)

EncodeTx returns a []byte or error

Types

type KVStore 

type KVStore = store.KVStore

KVStore re-exported for the sdk

type NamedStore added in v0.4.0 

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

NamedStore is used to provide scoped, read/write access to storage. Keys in the store are automatically prefixed with the given prefix name.

func NewNamedStore added in v0.4.0 

func NewNamedStore(serviceName string, store KVStore) NamedStore

NewNamedStore creates an instance

func (NamedStore) Delete added in v0.4.0 

func (ps NamedStore) Delete(key []byte)

Delete a key/value from the store

func (NamedStore) Get added in v0.4.0 

func (ps NamedStore) Get(key []byte) ([]byte, error)

Get something from the store by key

func (NamedStore) Has added in v0.4.0 

func (ps NamedStore) Has(key []byte) bool

Has : does the store contain the given key?

func (NamedStore) Put added in v0.4.0 

func (ps NamedStore) Put(key, value []byte) error

Put a key/value into the store

func (NamedStore) Query added in v0.4.0 

func (ps NamedStore) Query(key []byte) ([]byte, error)

Query a value by key from committed state

type Result 

type Result struct {
	Code uint32 // Any non-zero code is an error
	Data []byte
	Log  string
}

Result is it returned from a menta app TxHandler By default 'Code' will be zero which mean 'Ok' to tendermint

func ErrorBadTx 

func ErrorBadTx() Result

ErrorBadTx is returned when menta can't deserialize a Tx

func ErrorNoHandler 

func ErrorNoHandler() Result

ErrorNoHandler is returned when menta can't find a handler for a given route

func ResultError 

func ResultError(code uint32, log string) Result

ResultError is returned on an error with a non-zero code

type Service added in v0.3.0 

type Service interface {
	// Name is the unique name of the service. Used to register your service in Menta
	Name() string
	// Init is called once, on the very first run of the application.
	// Use this to load genesis data for your service
	Initialize(data []byte, store KVStore)
	// Execute is the primary business logic of your service. This is the blockchain
	// state transistion function
	Execute(sender []byte, msgid uint32, message []byte, store KVStore) Result
	// Query provides read access to storage.
	Query(key []byte, store KVStore) Result
}

Service is the primary interface to implement for application services. A given MentaApp may have 1 or more of these.
