Functions ¶
func Instrument ¶
func Instrument(requestDuration *prometheus.HistogramVec, instrumentationLabelOptions ...middleware.InstrumentationOption) ([]grpc.UnaryClientInterceptor, []grpc.StreamClientInterceptor)
func NewRateLimitRetrier ¶
func NewRateLimitRetrier(cfg backoff.Config) grpc.UnaryClientInterceptor
NewRateLimitRetrier creates a UnaryClientInterceptor which retries with backoff the calls from invoker when the executed RPC is rate limited.
func NewRateLimiter ¶
func NewRateLimiter(cfg *Config) grpc.UnaryClientInterceptor
NewRateLimiter creates a UnaryClientInterceptor for client side rate limiting.

Middleware []grpc.UnaryClientInterceptor `yaml:"-"`
StreamMiddleware []grpc.StreamClientInterceptor `yaml:"-"`
}
Config for a gRPC client.
func (*Config) CallOptions ¶
func (cfg *Config) CallOptions() []grpc.CallOption
CallOptions returns the config in terms of CallOptions.
func (*Config) DialOption ¶
func (cfg *Config) DialOption(unaryClientInterceptors []grpc.UnaryClientInterceptor, streamClientInterceptors []grpc.StreamClientInterceptor) ([]grpc.DialOption, error)
DialOption returns the config as a grpc.DialOptions. The passed inceptors wrap around the configured middleware.
func (*Config) RegisterFlags ¶
RegisterFlags registers flags.
func (*Config) RegisterFlagsWithPrefix ¶
RegisterFlagsWithPrefix registers flags with prefix.
