Types

type AddPeerPrm 

type AddPeerPrm struct {
	client.InvokePrmOptional

type Client 

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

Client is a wrapper over StaticClient which makes calls with the names and arguments of the FrostFS Netmap contract.

Working client must be created via constructor New. Using the Client that has been created with new(Client) expression (or just declaring a Client variable) is unsafe and can lead to panic.

func (c *Client) AddPeer(p AddPeerPrm) error

AddPeer registers peer in FrostFS network through Netmap contract call.

func (*Client) ContainerAliasFee 

func (c *Client) ContainerAliasFee() (uint64, error)

ContainerAliasFee returns additional fee paid by container owner to each alphabet node for container nice name registration.

func (*Client) ContainerFee 

func (c *Client) ContainerFee() (uint64, error)

ContainerFee returns fee paid by container owner to each alphabet node for container registration.

func (Client) ContractAddress 

func (c Client) ContractAddress() util.Uint160

ContractAddress returns the address of the associated contract.

func (*Client) Epoch 

func (c *Client) Epoch() (uint64, error)

func (*Client) EpochDuration 

func (c *Client) EpochDuration() (uint64, error)

EpochDuration returns number of sidechain blocks per one FrostFS epoch.

func (*Client) ForceRemovePeer added in v0.37.0 

func (c *Client) ForceRemovePeer(nodeInfo netmap.NodeInfo, vub uint32) (uint32, error)

ForceRemovePeer marks the given peer as offline via a notary control transaction. If vub > 0, vub will be used as valid until block value.

func (*Client) GetCandidates 

func (c *Client) GetCandidates() ([]netmap.NodeInfo, error)

GetCandidates calls "netmapCandidates" method and decodes []netmap.NodeInfo from the response.

func (*Client) GetInnerRingList 

func (c *Client) GetInnerRingList() (keys.PublicKeys, error)

GetInnerRingList return current IR list.

func (*Client) GetNetMap 

func (c *Client) GetNetMap(diff uint64) (*netmap.NetMap, error)

GetNetMap calls "snapshot" method and decodes netmap.NetMap from the response.

func (*Client) GetNetMapByEpoch 

func (c *Client) GetNetMapByEpoch(epoch uint64) (*netmap.NetMap, error)

GetNetMapByEpoch calls "snapshotByEpoch" method with the given epoch and decodes netmap.NetMap from the response.

func (*Client) HomomorphicHashDisabled 

func (c *Client) HomomorphicHashDisabled() (bool, error)

HomomorphicHashDisabled returns global configuration value of homomorphic hashing settings.

Returns (false, nil) if config key is not found in the contract.

func (*Client) InnerRingCandidateFee 

func (c *Client) InnerRingCandidateFee() (uint64, error)

InnerRingCandidateFee returns global configuration value of fee paid by node to be in inner ring candidates list.

func (*Client) LastEpochBlock 

func (c *Client) LastEpochBlock() (uint32, error)

LastEpochBlock receives block number of current FrostFS epoch through the Netmap contract call.

func (*Client) MaintenanceModeAllowed 

func (c *Client) MaintenanceModeAllowed() (bool, error)

MaintenanceModeAllowed reads admission of "maintenance" state from the FrostFS network configuration stored in the Sidechain. The admission means that storage nodes are allowed to switch their state to "maintenance".

By default, maintenance state is disallowed.

func (*Client) MaxObjectSize 

func (c *Client) MaxObjectSize() (uint64, error)

MaxObjectSize receives max object size configuration value through the Netmap contract call.

func (Client) Morph 

func (c Client) Morph() *client.Client

Morph returns raw morph client.

func (*Client) NetMap 

func (c *Client) NetMap() (*netmap.NetMap, error)
