Types

type ErrorCommunication

type ErrorCommunication string

ErrorCommunication errors are meant to be returned if the host and the renter seem to be miscommunicating. For example, if the renter attempts to pay an insufficient price, there has been a communication error.

func (ErrorCommunication) Error

func (ec ErrorCommunication) Error() string

Error satisfies the Error interface for the ErrorCommunication type.

type ErrorConnection

type ErrorConnection string

ErrorConnection is meant to be used on errors where the network is returning unexpected errors. For example, sudden disconnects or connection write failures.

func (ErrorConnection) Error

func (ec ErrorConnection) Error() string

Error satisfies the Error interface for the ErrorConnection type.

type ErrorConsensus

type ErrorConsensus string

ErrorConsensus errors are meant to be used when there are problems related to consensus, such as an inability to submit a storage proof to the blockchain, or an inability to get a file contract revision on to the blockchain.

func (ErrorConsensus) Error

func (ec ErrorConsensus) Error() string

Error satisfies the Error interface for the ErrorConsensus type.

type ErrorInternal

type ErrorInternal string

ErrorInternal errors are meant to be used if an internal process in the host is malfunctioning, for example if the disk is failing.

func (ErrorInternal) Error

func (ec ErrorInternal) Error() string

Error satisfies the Error interface for the ErrorInternal type.

type Host

type Host struct {
	modules.StorageManager
	// contains filtered or unexported fields
}

A Host contains all the fields necessary for storing files for clients and performing the storage proofs on the received files.

func New

func New(cs modules.ConsensusSet, g modules.Gateway, tpool modules.TransactionPool, wallet modules.Wallet, address string, persistDir string) (*Host, error)

New returns an initialized Host.

func (*Host) Announce

func (h *Host) Announce() error

Announce creates a host announcement transaction.

func (*Host) AnnounceAddress

func (h *Host) AnnounceAddress(addr modules.NetAddress) error

AnnounceAddress submits a host announcement to the blockchain to announce a specific address. If there is no error, the host's address will be updated to the supplied address.

func (*Host) Close

func (h *Host) Close() error

Close shuts down the host.

func (*Host) ConnectabilityStatus

func (h *Host) ConnectabilityStatus() modules.HostConnectabilityStatus

ConnectabilityStatus returns the connectability state of the host, whether the host can connect to itself on its configured netaddress.

func (*Host) ExternalSettings

func (h *Host) ExternalSettings() modules.HostExternalSettings

ExternalSettings returns the hosts external settings. These values cannot be set by the user (host is configured through InternalSettings), and are the values that get displayed to other hosts on the network.

func (*Host) FinancialMetrics

func (h *Host) FinancialMetrics() modules.HostFinancialMetrics

FinancialMetrics returns information about the financial commitments, rewards, and activities of the host.

func (*Host) InternalSettings

func (h *Host) InternalSettings() modules.HostInternalSettings

InternalSettings returns the settings of a host.

func (*Host) NetAddress

func (h *Host) NetAddress() modules.NetAddress

NetAddress returns the address at which the host can be reached.

func (*Host) NetworkMetrics

func (h *Host) NetworkMetrics() modules.HostNetworkMetrics

NetworkMetrics returns information about the types of rpc calls that have been made to the host.

func (*Host) ProcessConsensusChange

func (h *Host) ProcessConsensusChange(cc modules.ConsensusChange)

ProcessConsensusChange will be called by the consensus set every time there is a change to the blockchain.

func (*Host) PruneStaleStorageObligations

func (h *Host) PruneStaleStorageObligations() error

PruneStaleStorageObligations will delete storage obligations from the host that, for whatever reason, did not make it on the block chain. As these stale storage obligations have an impact on the host financial metrics, this method updates the host financial metrics to show the correct values.

func (*Host) PublicKey

func (h *Host) PublicKey() types.SiaPublicKey

PublicKey returns the public key of the host that is used to facilitate relationships between the host and renter.

func (*Host) SetInternalSettings

func (h *Host) SetInternalSettings(settings modules.HostInternalSettings) error

SetInternalSettings updates the host's internal HostInternalSettings object.

func (*Host) StorageObligations

func (h *Host) StorageObligations() (sos []modules.StorageObligation)

StorageObligations fetches the set of storage obligations in the host and returns metadata on them.

func (*Host) WorkingStatus

func (h *Host) WorkingStatus() modules.HostWorkingStatus

WorkingStatus returns the working state of the host, where working is defined as having received more than workingStatusThreshold settings calls over the period of workingStatusFrequency.
