Variables

var ErrNilClient = errors.New("netmap contract client is nil")

ErrNilClient is returned by functions that expect a non-nil Client pointer, but received nil.

Functions

func IntegerAssert

func IntegerAssert(item stackitem.Item) (interface{}, error)

Types

type AddPeerArgs

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

AddPeerArgs groups the arguments of add peer invocation call.

func (*AddPeerArgs) SetInfo

func (a *AddPeerArgs) SetInfo(v []byte)

SetInfo sets the peer information.

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 NeoFS 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 New

func New(c *client.StaticClient, opts ...Option) (*Client, error)

New creates, initializes and returns the Client instance.

If StaticClient is nil, client.ErrNilStaticClient is returned.

Other values are set according to provided options, or by default:

• add peer method name: AddPeer;
• new epoch method name: NewEpoch;
• get network map method name: Netmap;
• update state method name: UpdateState;
• inner ring list method name: InnerRingList.

If desired option satisfies the default value, it can be omitted. If multiple options of the same config value are supplied, the option with the highest index in the arguments will be used.

func (*Client) AddPeer

func (c *Client) AddPeer(args AddPeerArgs) error

AddPeer invokes the call of add peer method of NeoFS Netmap contract.

func (*Client) Config

func (c *Client) Config(args ConfigArgs, assert func(stackitem.Item) (interface{}, error)) (*ConfigValues, error)

Epoch performs the test invoke of get epoch number method of NeoFS Netmap contract.

func (*Client) EpochSnapshot

func (c *Client) EpochSnapshot(args EpochSnapshotArgs) (*EpochSnapshotValues, error)

EpochSnapshot performs the test invoke of get snapshot of network map by epoch from NeoFS Netmap contract.

func (*Client) InnerRingList

func (c *Client) InnerRingList(args InnerRingListArgs) (*InnerRingListValues, error)

InnerRingList performs the test invoke of inner ring list method of NeoFS Netmap contract.

func (*Client) NetMap
