Types

type GenesisBuilder

type GenesisBuilder interface {
	CreateDefaultConfig() ([]byte, error)
	BuildConfig(config []byte) error
}

type Module

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

Module implements the GenesisBuilder Runtime API definition.

For more information about API definition, see: https://github.com/paritytech/polkadot-sdk/blob/master/substrate/primitives/genesis-builder/src/lib.rs#L38

func New

func New(modules []primitives.Module, logger log.RuntimeLogger) Module

func (Module) BuildConfig

func (m Module) BuildConfig(dataPtr int32, dataLen int32) int64

BuildConfig validates the genesis configuration and stores it in the storage. It takes two arguments: - dataPtr: Pointer to the data in the Wasm memory. - dataLen: Length of the data. which represent the SCALE-encoded serialised JSON genesis configuration. The serialised bytes must contain the genesis configuration for each runtime module.

func (Module) CreateDefaultConfig

func (m Module) CreateDefaultConfig() int64

CreateDefaultConfig returns the default genesis configuration of the runtime. Includes all modules' JSON default configuration. Returns a pointer-size of the serialised JSON representation of the default genesis configuration.

func (Module) Item

func (m Module) Item() primitives.ApiItem

Item returns the first 8 bytes of the Blake2b hash of the name and version of the api module.

func (Module) Name

func (m Module) Name() string

Name returns the name of the api module.
