Functions

func ConvertError

func ConvertError(err error, msg string, defaultCode codes.Code) error

ConvertError converts a generic error into a grpc status error. The input may either be a status.Error already, or standard error type. Any error that matches on of the common status code mappings will be converted, all unmatched errors will be converted to the provided defaultCode.

func ConvertMultiError

func ConvertMultiError(err *multierror.Error, msg string, defaultCode codes.Code) error

ConvertMultiError converts a multierror to a grpc status error. If the errors have related status codes, the common code is returned, otherwise defaultCode is used.

func ConvertStorageError

func ConvertStorageError(err error) error

ConvertStorageError converts a generic error into a grpc status error, converting storage errors into codes.NotFound

func LoggingInterceptor

func LoggingInterceptor(log zerolog.Logger) []grpc.UnaryServerInterceptor

LoggingInterceptor creates the logging interceptors to log incoming GRPC request and response (minus the payload body)

func NewRateLimiterInterceptor

func NewRateLimiterInterceptor(log zerolog.Logger, apiRateLimits map[string]int, apiBurstLimits map[string]int) *rateLimiterInterceptor

NewRateLimiterInterceptor creates a new rate limiter interceptor with the defined per second rate limits and the optional burst limit for each API.
