func (eth *Ethereum) StateAtBlock(block *types.Block, reexec uint64, base *state.StateDB, checkLive bool, preferDisk bool) (statedb *state.StateDB, err error)

StateAtBlock retrieves the state database associated with a certain block. If no state is locally available for the given block, a number of blocks are attempted to be reexecuted to generate the desired state. The optional base layer statedb can be passed then it's regarded as the statedb of the parent block. Parameters:

  • block: The block for which we want the state (== state at the stateRoot of the parent)
  • reexec: The maximum number of blocks to reprocess trying to obtain the desired state
  • base: If the caller is tracing multiple blocks, the caller can provide the parent state continuously from the callsite.
  • checklive: if true, then the live 'blockchain' state database is used. If the caller want to perform Commit or other 'save-to-disk' changes, this should be set to false to avoid storing trash persistently
  • preferDisk: this arg can be used by the caller to signal that even though the 'base' is provided, it would be preferable to start from a fresh state, if we have it on disk.

func (s *Ethereum) Stop() error

Stop implements node.Lifecycle, terminating all internal goroutines used by the Ethereum protocol. FIXME remove error from type if this will never return an error

}
var DefaultSettings Settings = Settings{MaxBlocksPerRequest: 2000}

type StorageRangeResult

type StorageRangeResult struct {
	Storage storageMap   `json:"storage"`
	NextKey *common.Hash `json:"nextKey"` // nil if Storage includes the last key in the trie.
}

StorageRangeResult is the result of a debug_storageRangeAt API call.
