Constants ¶
const CustomErrorMetadataKey = "Custom-Error"
CustomErrorMetadataKey is the name of the metadata key storing additional error information. Metadata value is expected to be a byte-encoded JSON object.
const HttpCodeMetadataKey = "X-Http-Code"
HttpCodeMetadataKey is the key to use when setting custom HTTP status codes in gRPC metadata.
const MetadataPrefix = "Grpc-Metadata"
MetadataPrefix is the prefix for grpc headers on metadata

Functions ¶
func AppendCustomErrorHeader ¶
AppendCustomErrorHeader sets a CustomErrorMetadataKey gRPC header on the passed in context, using the passed in error data as the header's value. The data is serialized as JSON.
func AppendHeaders ¶
AppendHeaders parses the provided GRPC headers and attaches them to the provided context.
func LogRequests ¶
func LogRequests( ctx context.Context, method string, req, reply interface{}, cc *grpc.ClientConn, invoker grpc.UnaryInvoker, opts ...grpc.CallOption, ) error
LogRequests logs the gRPC backend as well as request duration when the log level is set to debug or higher.
func LogStream ¶
func LogStream( ctx context.Context, sd *grpc.StreamDesc, conn *grpc.ClientConn, method string, streamer grpc.Streamer, opts ...grpc.CallOption, ) (grpc.ClientStream, error)
LogStream prints the method at DEBUG level at the start of the stream.
func WithPrefix ¶
WithPrefix creates a new string with grpc metadata prefix
