Variables

var RetryOption grpc.CallOption = grpc_retry.WithPerRetryTimeout(3 * time.Second)

var RetryProfile = []grpc.CallOption{
	RetryOption,
}

RetryProfile is the common retry profile for RPCs.

Types

type AddressRewriter

type AddressRewriter interface {
	RedirectToQUIC(ctx context.Context, address net.Addr) (net.Addr, bool, error)
}

AddressRewriter redirects to QUIC endpoints.

type ConnDialer

type ConnDialer interface {
	Dial(context.Context, net.Addr) (net.Conn, error)
}

ConnDialer dials a net.Conn.

type ConnectionStater

type ConnectionStater interface {
	ConnectionState() tls.ConnectionState
}

type Dialer

type Dialer interface {
	// DialContext creates a client connection to the given target.
	Dial(context.Context, net.Addr) (*grpc.ClientConn, error)
}

Dialer creates a gRPC client connection to the given target.

type PassThroughCredentials

type PassThroughCredentials struct{}

PassThroughCredentials implements the grpc/credentials.TransportCredentials interface. It allows to pass the TLS connection state of an underlying TLS connection, e.g. from an underlying QUIC session, into the grpc stack. This allows accessing this information in the context of grpc/peer.Peer.AuthInfo. The handshake methods only extract the TLS state and otherwise simply pass-through the underlying connection object. The underlying connection must implement the ConnectionStater interface.

func (PassThroughCredentials) ClientHandshake

func (c PassThroughCredentials) ClientHandshake(
	ctx context.Context,
	authority string,
	conn net.Conn,
) (net.Conn, credentials.AuthInfo, error)

func (PassThroughCredentials) Clone

func (c PassThroughCredentials) Clone() credentials.TransportCredentials

func (PassThroughCredentials) Info

func (c PassThroughCredentials) Info() credentials.ProtocolInfo

func (PassThroughCredentials) OverrideServerName

func (c PassThroughCredentials) OverrideServerName(string) error

func (PassThroughCredentials) ServerHandshake

func (c PassThroughCredentials) ServerHandshake(
	conn net.Conn,
) (net.Conn, credentials.AuthInfo, error)

type QUICDialer

type QUICDialer struct {
	Rewriter AddressRewriter
	Dialer   ConnDialer
}

QUICDialer dials a gRPC connection over QUIC/SCION. This dialer is meant to be used for inter AS communication, and is capable of resolving svc addresses.

func (*QUICDialer) Dial

func (d *QUICDialer) Dial(ctx context.Context, addr net.Addr) (*grpc.ClientConn, error)

Dial dials a gRPC connection over QUIC/SCION.

type SimpleDialer

type SimpleDialer struct{}

SimpleDialer implements a wrapper around grpc.DialContext that implements the dialer interface. It simply uses the string of the address to dial.

func (SimpleDialer) Dial

func (SimpleDialer) Dial(ctx context.Context, address net.Addr) (*grpc.ClientConn, error)

Dial dials the address by converting it to a string.

type TCPDialer

type TCPDialer struct {
	SvcResolver func(addr.SVC) []resolver.Address
}

TCPDialer dials a gRPC connection over TCP. This dialer is meant to be used for AS internal communication, and is capable of resolving svc addresses.

func (*TCPDialer) Dial

func (t *TCPDialer) Dial(ctx context.Context, dst net.Addr) (*grpc.ClientConn, error)

Dial dials a gRPC connection over TCP. It resolves svc addresses.
