You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: metrics.go
    path of file: ./repos/cockroach/pkg/kv/kvserver/batcheval/result
    
    the code of the file until where you have to start completion: // Copyright 2014 The Cockroach Auth
    
func (mt *Metrics) Add(o Metrics) {
	mt.LeaseRequestSuccess += o.LeaseRequestSuccess
	mt.LeaseRequestError += o.LeaseRequestError
	mt.LeaseTransferSuccess += o.LeaseTransferSuccess
	mt.LeaseTransferError += o.LeaseTransferError
	mt.ResolveCommit += o.ResolveCommit
	mt.ResolveAbort += o.ResolveAbort
	mt.ResolvePoison += o.ResolvePoison
	mt.AddSSTableAsWrites += o.AddSSTableAsWrites
}
