	opts []grpc.DialOption,
) *rpc.ClientCfg

func BuildConnBase 

func BuildConnBase(tlsPath, fullAddr string, opts []grpc.DialOption) *rpc.ClientCfg

Types

type Conn 

type Conn struct {
	*grpc.ClientConn
	// contains filtered or unexported fields
}

func TryAuthOpen 

func TryAuthOpen(jwtToken string, conf *rpc.ClientCfg) (c Conn)

func TryAuthOpenWithSleep added in v0.1.28 

func TryAuthOpenWithSleep(
	jwtToken string,
	conf *rpc.ClientCfg,
	s func(d time.Duration),
) (
	c Conn,
)

TryAuthOpenWithSleep opens authorized gRPC connection with sleep time. nolintlint

func TryOpen 

func TryOpen(user string, conf *rpc.ClientCfg) (c Conn)

func (Conn) DoRelease 

func (conn Conn) DoRelease(ctx context.Context, id *agency.ProtocolID, cOpts ...grpc.CallOption) (pid *agency.ProtocolID, err error)

func (Conn) DoResume 

func (conn Conn) DoResume(ctx context.Context, state *agency.ProtocolState, cOpts ...grpc.CallOption) (pid *agency.ProtocolID, err error)

func (Conn) DoStart 

func (conn Conn) DoStart(ctx context.Context, protocol *agency.Protocol, cOpts ...grpc.CallOption) (pid *agency.ProtocolID, err error)

func (Conn) DoStatus 

func (conn Conn) DoStatus(ctx context.Context, id *agency.ProtocolID, cOpts ...grpc.CallOption) (status *agency.ProtocolStatus, err error)

func (Conn) Listen 

func (conn Conn) Listen(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.Question,
	err error,
)

Listen listens both status notifications and agent questions. Client is specified by clientID. Both notifications and questions arriwe from same channel which is Question type.

func (Conn) ListenAndRetry 

func (conn Conn) ListenAndRetry(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.Question,
)

ListenAndRetry listens both status notifications and agent questions. Client is specified by clientID. Both notifications and questions arriwe from same channel which is Question type. NOTE! This function handles connection errors by itself i.e. it tries to reopen error connnections until its terminated by ctx.Cancel. The actual retry logic is implemented in ListenStatusAndRetry and WaitAndRetry functions.

func (Conn) ListenStatus 

func (conn Conn) ListenStatus(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.AgentStatus,
	err error,
)

ListenStatus listens agent notification statuses. Client connection is identifed by ClientID. NOTE! The function filters KEEPALIVE messages.

func (Conn) ListenStatusAndRetry 

func (conn Conn) ListenStatusAndRetry(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	sch chan *agency.AgentStatus,
)

ListenStatusAndRetry listens agent notification statuses. Client connection is identifed by ClientID. NOTE! This function handles connection errors by itself i.e. it tries to reopen error connnections until its terminated by ctx.Cancel. NOTE! The function filters KEEPALIVE messages.

func (Conn) ListenStatusErr 

func (conn Conn) ListenStatusErr(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.AgentStatus,
	errCh chan error,
	err error,
)

ListenStatusErr listens agent notification statuses. It terminates on an error and transports it to the caller thru the error channel. Client connection is identifed by ClientID. NOTE! The function filters KEEPALIVE messages.

func (Conn) PSMHook 

func (conn Conn) PSMHook(ctx context.Context, cOpts ...grpc.CallOption) (ch chan *ops.AgencyStatus, err error)

func (Conn) Wait 

func (conn Conn) Wait(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.Question,
	err error,
)

Wait listens agent notification questions. It terminates on error and closes the returned listening channel. Client connection is identifed by ClientID. NOTE! The function filters KEEPALIVE messages.

func (Conn) WaitAndRetry 

func (conn Conn) WaitAndRetry(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.Question,
)

WaitAndRetry listens agent notification questions. Client connection is identifed by ClientID. NOTE! This function handles connection errors by itself i.e. it tries to reopen error connnections until its terminated by ctx.Cancel. NOTE! The function filters KEEPALIVE messages.

func (Conn) WaitErr 

func (conn Conn) WaitErr(
	ctx context.Context,
	client *agency.ClientID,
	cOpts ...grpc.CallOption,
) (
	ch chan *agency.Question,
	errCh chan error,
	err error,
)

WaitErr listens agent notification questions. It terminates on an error and transports it to the caller thru an error channel. Client connection is identifed by ClientID. NOTE! The function filters KEEPALIVE messages.

type Pairwise

func (pw *Pairwise) Connection(

)

Connection is a helper wrapper to start a connection protocol in the agency. The invitationStr accepts both JSON and URL formated invitations. The agency does the same.
