func IsClosedConnection(err error) bool

IsClosedConnection returns true if err is an error produced by gRPC on closed connections.

func IsGRPCRequest ¶

func IsGRPCRequest(r *http.Request) bool

IsGRPCRequest returns true if r came from a grpc client.

Its logic is a partial recreation of gRPC's internal checks, see https://github.com/grpc/grpc-go/blob/01de3de/transport/handler_server.go#L61:L69
