Functions

func Dial

func Dial(hostName string, tlsConfig *tls.Config) (*grpc.ClientConn, error)

Dial creates a client connection to the given target with default options. The hostName syntax is defined in https://github.com/grpc/grpc/blob/master/doc/naming.md. e.g. to use dns resolver, a "dns:///" prefix should be applied to the target.

func NewContextFromParentWithTimeoutAndHeaders

func NewContextFromParentWithTimeoutAndHeaders(parentCtx context.Context, timeout time.Duration) (context.Context, context.CancelFunc)

NewContextFromParentWithTimeoutAndHeaders creates context from parent context with timeout and version headers.

func NewContextWithCLIHeaders

func NewContextWithCLIHeaders() (context.Context, context.CancelFunc)

NewContextWithCLIHeaders creates context with version headers for CLI.

func NewContextWithTimeout

func NewContextWithTimeout(timeout time.Duration) (context.Context, context.CancelFunc)

NewContextWithTimeout creates context with timeout.

func NewContextWithTimeoutAndCLIHeaders

func NewContextWithTimeoutAndCLIHeaders(timeout time.Duration) (context.Context, context.CancelFunc)

NewContextWithTimeoutAndCLIHeaders creates context with timeout and version headers for CLI.

func NewContextWithTimeoutAndHeaders

func NewContextWithTimeoutAndHeaders(timeout time.Duration) (context.Context, context.CancelFunc)

NewContextWithTimeoutAndHeaders creates context with timeout and version headers.

func ServiceErrorInterceptor

func ServiceErrorInterceptor(ctx context.Context, req interface{}, _ *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (interface{}, error)
