Types

type ADNLRequest 

type ADNLRequest struct {
	QueryID  []byte
	Data     any
	RespChan chan *ADNLResponse
}

type ADNLResponse 

type ADNLResponse struct {
	Data tl.Serializable
	Err  error
}

type ConfigBlock 

type ConfigBlock struct {
	Workchain int32  `json:"workchain"`
	Shard     int64  `json:"shard"`
	SeqNo     uint32 `json:"seqno"`
	RootHash  []byte `json:"root_hash"`
	FileHash  []byte `json:"file_hash"`
}

type ConnectionPool 

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

func NewConnectionPool 

func NewConnectionPool() *ConnectionPool

NewConnectionPool - ordinary pool to query liteserver

func NewConnectionPoolWithAuth 

func NewConnectionPoolWithAuth(key ed25519.PrivateKey) *ConnectionPool

NewConnectionPoolWithAuth - will do TCP authorization after connection, can be used to communicate with storage-daemon

func (*ConnectionPool) AddConnection 

func (c *ConnectionPool) AddConnection(ctx context.Context, addr, serverKey string, clientKey ...ed25519.PrivateKey) error

func (*ConnectionPool) AddConnectionsFromConfig 

func (c *ConnectionPool) AddConnectionsFromConfig(ctx context.Context, config *GlobalConfig) error

func (*ConnectionPool) AddConnectionsFromConfigFile 

func (c *ConnectionPool) AddConnectionsFromConfigFile(configPath string) error

func (*ConnectionPool) AddConnectionsFromConfigUrl 

func (c *ConnectionPool) AddConnectionsFromConfigUrl(ctx context.Context, configUrl string) error

func (*ConnectionPool) DefaultReconnect 

func (c *ConnectionPool) DefaultReconnect(waitBeforeReconnect time.Duration, maxTries int) OnDisconnectCallback

func (*ConnectionPool) QueryADNL 

func (c *ConnectionPool) QueryADNL(ctx context.Context, request tl.Serializable, result tl.Serializable) error

QueryADNL - sends ADNL request to peer

func (*ConnectionPool) QueryLiteserver 

func (c *ConnectionPool) QueryLiteserver(ctx context.Context, request tl.Serializable, result tl.Serializable) error

QueryLiteserver - sends request to liteserver

func (*ConnectionPool) SetOnDisconnect 

func (c *ConnectionPool) SetOnDisconnect(cb OnDisconnectCallback)

func (*ConnectionPool) StickyContext 

func (c *ConnectionPool) StickyContext(ctx context.Context) context.Context

StickyContext - bounds all requests with this context to the same lite-server node, if possible. This is useful when we are doing some requests which depends on each other.

For example: we requested MasterchainInfo from node A, and we are trying to request account with this block info from node B but node B don't have yet information about this block, so it can return error. If we use StickyContext, all requests where its passed will be routed to same node.

In case if sticky node goes down, default balancer will be used as fallback

func (*ConnectionPool) StickyContextNextNode 

func (c *ConnectionPool) StickyContextNextNode(ctx context.Context) (context.Context, error)

func (*ConnectionPool) StickyContextWithNodeID 

func (c *ConnectionPool) StickyContextWithNodeID(ctx context.Context, nodeId uint32) context.Context

func (*ConnectionPool) StickyNodeID 

func (c *ConnectionPool) StickyNodeID(ctx context.Context) uint32

func (*ConnectionPool) Stop 

func (c *ConnectionPool) Stop()
