const DEFAULT_MAX_REQUEST_SIZE = 100 << 20 // 100 MiB

handler must be pointer to a struct with function fields Returned value closes the client connection TODO: Example

func NewMergeClient

func NewMergeClient(ctx context.Context, addr string, namespace string, outs []interface{}, requestHeader http.Header, opts ...Option) (ClientCloser, error)

NewMergeClient is like NewClient, but allows to specify multiple structs to be filled in the same namespace, using one connection

type Config

type Config struct {
	// contains filtered or unexported fields
}

type ErrClient
