Types

type Wrapper

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

Wrapper is a wrapper over netmap contract client which implements:

• network map storage;
• tool for peer state updating.

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

func NewFromMorph

func NewFromMorph(cli *client.Client, contract util.Uint160, fee fixedn.Fixed8, opts ...client.StaticClientOption) (*Wrapper, error)

NewFromMorph returns the wrapper instance from the raw morph client.

func (*Wrapper) AddPeer

func (w *Wrapper) AddPeer(nodeInfo *netmap.NodeInfo) error

AddPeer registers peer in NeoFS network through Netmap contract call.

func (*Wrapper) AuditFee

func (w *Wrapper) AuditFee() (uint64, error)

AuditFee returns audit fee configuration value from network config in netmap contract.

func (*Wrapper) BasicIncomeRate

func (w *Wrapper) BasicIncomeRate() (uint64, error)

BasicIncomeRate returns basic income rate configuration value from network config in netmap contract.

func (*Wrapper) ContainerFee

func (w *Wrapper) ContainerFee() (uint64, error)

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

func (*Wrapper) EigenTrustAlpha

func (w *Wrapper) EigenTrustAlpha() (float64, error)

EigenTrustAlpha returns global configuration value of alpha parameter. It receives the alpha as a string and tries to convert it to float.

func (*Wrapper) EigenTrustIterations

func (w *Wrapper) EigenTrustIterations() (uint64, error)

EigenTrustIterations returns global configuration value of iteration cycles for EigenTrust algorithm per epoch.

func (*Wrapper) Epoch

func (w *Wrapper) Epoch() (uint64, error)

Epoch receives number of current NeoFS epoch through the Netmap contract call.

func (*Wrapper) EpochDuration

func (w *Wrapper) EpochDuration() (uint64, error)

EpochDuration returns number of sidechain blocks per one NeoFS epoch.

func (Wrapper) GetCandidates

func (w Wrapper) GetCandidates() (*netmap.Netmap, error)

GetCandidates receives information list about candidates for the next epoch network map through the Netmap contract call, composes network map from them and returns it.

func (Wrapper) GetNetMap

func (w Wrapper) GetNetMap(diff uint64) (*netmap.Netmap, error)

GetNetMap receives information list about storage nodes through the Netmap contract call, composes network map from them and returns it. With diff == 0 returns current network map, else return snapshot of previous network map.

func (Wrapper) GetNetMapByEpoch

func (w Wrapper) GetNetMapByEpoch(epoch uint64) (*netmap.Netmap, error)

GetNetMapByEpoch receives information list about storage nodes through the Netmap contract call, composes network map from them and returns it. Returns snapshot of the specified epoch number.

func (*Wrapper) InnerRingCandidateFee

func (w *Wrapper) InnerRingCandidateFee() (uint64, error)

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

func (*Wrapper) MaxObjectSize

func (w *Wrapper) MaxObjectSize() (uint64, error)

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

func (*Wrapper) NewEpoch

func (w *Wrapper) NewEpoch(e uint64) error

NewEpoch updates NeoFS epoch number through Netmap contract call.

func (*Wrapper) SetConfig

func (w *Wrapper) SetConfig(id, key []byte, value interface{}) error

SetConfig sets config field.

func (*Wrapper) SetInnerRing

func (w *Wrapper) SetInnerRing(keys keys.PublicKeys) error

SetInnerRing updates inner ring keys.

func (*Wrapper) Snapshot

func (w *Wrapper) Snapshot() (*netmap.Netmap, error)

Snapshot returns current netmap node infos. Consider using pkg/morph/client/netmap for this.

func (*Wrapper) UpdatePeerState

func (w *Wrapper) UpdatePeerState(key []byte, state netmap.NodeState) error

UpdatePeerState changes peer status through Netmap contract call.

func (*Wrapper) WithdrawFee

func (w *Wrapper) WithdrawFee() (uint64, error)

WithdrawFee returns global configuration value of fee paid by user to withdraw assets from NeoFS contract.
