var NewBlockRetainerEvents = event.CreateGroupConstructor(func() (newEvents *BlockRetainerEvents) {
	return &BlockRetainerEvents{
		BlockRetained:  event.New1[*blocks.Block](),
		BlockAccepted:  event.New1[*blocks.Block](),
		BlockConfirmed: event.New1[*blocks.Block](),

})

NewBlockRetainerEvents contains the constructor of the Events object (it is generated by a generic factory).

var NewTransactionRetainerEvents = event.CreateGroupConstructor(func() (newEvents *TransactionRetainerEvents) {
	return &TransactionRetainerEvents{
		TransactionRetained: event.New1[iotago.TransactionID](),
	}
})

NewTransactionRetainerEvents contains the constructor of the Events object (it is generated by a generic factory).

Types

type BlockRetainer

type BlockRetainer interface {
	BlockMetadata(blockID iotago.BlockID) (*api.BlockMetadataResponse, error)

	// Reset resets the component to a clean state as if it was created at the last commitment.
	Reset()

	// Interface embeds the required methods of the module.Module.
	module.Module
}

BlockRetainer keeps and resolves all the block related information needed in the API and INX.

type BlockRetainerEvents

type BlockRetainerEvents struct {
	// BlockRetained is triggered when a block is stored in the retainer.
	BlockRetained *event.Event1[*blocks.Block]
	// BlockAccepted is triggered when a block is stored in the retainer caused by a block acceptance event.
	BlockAccepted *event.Event1[*blocks.Block]
	// BlockConfirmed is triggered when a block is stored in the retainer caused by a block confirmed event.
	BlockConfirmed *event.Event1[*blocks.Block]

	event.Group[BlockRetainerEvents, *BlockRetainerEvents]
}

BlockRetainerEvents is a collection of Retainer related BlockRetainerEvents.

type TransactionRetainer

type TransactionRetainer interface {
	// TransactionMetadata returns the metadata of a transaction.
	TransactionMetadata(txID iotago.TransactionID) (*api.TransactionMetadataResponse, error)

	// Reset resets the component to a clean state as if it was created at the last commitment.
	Reset(targetSlot iotago.SlotIndex)

	module.Module
}

TransactionRetainer keeps and resolves all the transaction-related metadata needed in the API and INX.

type TransactionRetainerEvents

type TransactionRetainerEvents struct {
	// TransactionRetained is triggered when a transaction is stored in the retainer.
	TransactionRetained *event.Event1[iotago.TransactionID]

	event.Group[TransactionRetainerEvents, *TransactionRetainerEvents]
}

TransactionRetainerEvents is a collection of Retainer related TransactionRetainerEvents.
