Types ¶
type BaseResult ¶
type BaseResult struct {
// Code is to determine if the action succeeded.
Code StatusCode
// Message may contain DA layer specific information (like DA block height/hash, detailed error message, etc)
Message string
// DAHeight informs about a height on Data Availability Layer for given result.
DAHeight uint64
}
BaseResult contains basic information returned by DA layer.
type BatchRetriever ¶
type BatchRetriever interface {
// RetrieveBatches returns blocks at given data layer height from data availability layer.
RetrieveBatches(dataLayerHeight uint64) ResultRetrieveBatch
}
BatchRetriever is additional interface that can be implemented by Data Availability Layer Client that is able to retrieve block data from DA layer. This gives the ability to use it for block synchronization.
type DataAvailabilityLayerClient ¶
type DataAvailabilityLayerClient interface {
// Init is called once to allow DA client to read configuration and initialize resources.
Init(config []byte, kvStore store.KVStore, logger log.Logger) error
// Start is called once, after Init. It's implementation should start operation of DataAvailabilityLayerClient.
Start() error
// Stop is called once, when DataAvailabilityLayerClient is no longer needed.
Stop() error
// SubmitBatch submits the passed in block to the DA layer.
// This should create a transaction which (potentially)
// triggers a state transition in the DA layer.
SubmitBatch(batch *types.Batch) ResultSubmitBatch
// CheckBatchAvailability queries DA layer to check data availability of block corresponding at given height.
CheckBatchAvailability(dataLayerHeight uint64) ResultCheckBatch
GetClientType() Client
}
DataAvailabilityLayerClient defines generic interface for DA layer block submission. It also contains life-cycle methods.
type ResultCheckBatch ¶
type ResultCheckBatch struct {
BaseResult
// DataAvailable is the actual answer whether the block is available or not.
// It can be true if and only if Code is equal to StatusSuccess.
DataAvailable bool
}
ResultCheckBatch contains information about block availability, returned from DA layer client.
type ResultRetrieveBatch ¶
type ResultRetrieveBatch struct {
BaseResult
// Block is the full block retrieved from Data Availability Layer.
// If Code is not equal to StatusSuccess, it has to be nil.
Batches []*types.Batch
}
ResultRetrieveBatch contains batch of blocks returned from DA layer client.
type ResultSubmitBatch ¶
type ResultSubmitBatch struct {
BaseResult
}
ResultSubmitBatch contains information returned from DA layer after block submission.
type StatusCode ¶
type StatusCode uint64
StatusCode is a type for DA layer return status. TODO: define an enum of different non-happy-path cases that might need to be handled by Dymint independent of the underlying DA chain.
const ( StatusUnknown StatusCode = iota StatusSuccess StatusTimeout StatusError )
Data Availability return codes.
