Types

type AdditionalOperationsModule

type AdditionalOperationsModule interface {
	// RunAdditionalOperations runs all the additional operations required by the module.
	// This is the perfect place where to initialize all the operations that subscribe to websockets or other
	// external sources.
	// NOTE. This method will only be run ONCE before starting the parsing of the blocks.
	RunAdditionalOperations() error
}

type AsyncOperationsModule

type AsyncOperationsModule interface {
	// RunAsyncOperations runs all the async operations associated with a module.
	// This method will be run on a separate goroutine, that will stop only when the user stops the entire process.
	// For this reason, this method cannot return an error, and all raised errors should be signaled by panicking.
	RunAsyncOperations()
}

type BlockModule

type BlockModule interface {
	// HandleBlock allows to handle a single block.
	// For convenience of use, all the transactions present inside the given block will be passed as well.
	// For each transaction present inside the block, HandleTx will be called as well.
	// NOTE. The returned error will be logged using the BlockError method. All other modules' handlers
	// will still be called.
	HandleBlock(block *tmctypes.ResultBlock, results *tmctypes.ResultBlockResults, txs []*types.Tx, vals *tmctypes.ResultValidators) error
}

type FastSyncModule

type FastSyncModule interface {
	// DownloadState allows to download the module state at the given height.
	// This will be called only when the fast sync is used, and only once for the initial height.
	// It should query the gRPC and get all the possible data.
	// NOTE. If an error is returned, following modules will still be called.
	DownloadState(height int64) error
}

type GenesisModule

type GenesisModule interface {
	// HandleGenesis allows to handle the genesis state.
	// For convenience of use, the already-unmarshalled AppState is provided along with the full GenesisDoc.
	// NOTE. The returned error will be logged using the GenesisError method. All other modules' handlers
	// will still be called.
	HandleGenesis(doc *tmtypes.GenesisDoc, appState map[string]json.RawMessage) error
}

type MessageModule

type MessageModule interface {
	// HandleMsg handles a single message.
	// For convenience of usa, the index of the message inside the transaction and the transaction itself
	// are passed as well.
	// NOTE. The returned error will be logged using the MsgError method. All other modules' handlers
	// will still be called.
	HandleMsg(index int, msg sdk.Msg, tx *types.Tx) error
}

type Module

type Module interface {
	// Name returns the module name
	Name() string
}

Module represents a generic module without any particular handling of data

type Modules

type Modules []Module

Modules represents a slice of Module objects

func (Modules) FindByName

func (m Modules) FindByName(name string) (module Module, found bool)

FindByName returns the module having the given name inside the m slice. If no modules are found, returns nil and false.

type PeriodicOperationsModule

type PeriodicOperationsModule interface {
	// RegisterPeriodicOperations allows to register all the operations that will be run on a periodic basis.
	// The given scheduler can be used to define the periodicity of each task.
	// NOTE. This method will only be run ONCE during the module initialization.
	RegisterPeriodicOperations(scheduler *gocron.Scheduler) error
}

type TransactionModule

type TransactionModule interface {
	// HandleTx handles a single transaction.
	// For each message present inside the transaction, HandleMsg will be called as well.
	// NOTE. The returned error will be logged using the TxError method. All other modules' handlers
	// will still be called.
	HandleTx(tx *types.Tx) error
}
