Variables

var ErrHistoryPruned = errors.New("no commit info found (history pruned)")

ErrHistoryPruned indicates that the necessary state for the requested height isn't found in the store.

Functions

func IsErrHistoryPruned

func IsErrHistoryPruned(err error) bool

IsErrHistoryPruned reports whether the input error matches the CosmosSDK errors returned when the state for the requested height isn't found in the store.

Types

type Provider

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