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: postrespgenerator.go
    path of file: ./repos/aether-app/aether-core/aether/backend/responsegenerator
    
    the code of the file until where you have to start completion: // Backend > ResponseGenerator > PostRespGenerator
// This file provides a set of functions that relate to the generation of non-pregenerated post responses based on the network requests, and their reuse.

package responsegenerator

import (
	// "fmt"
	"aether-core/aether/backend/metrics"
	"aether-core/aether/io/api"
	"aether-core/aether/io/persistence"

func insertIntoPOSTResponseReuseTracker(resultPage *api.ApiResponse, foldername string, dbReadStartLoc api.Timestamp) {
	pg := *resultPage // we can take a look at only one page because we know all are the same.
	// Rules: A reusable response can only have a time range filter (timestamp) and it can only have one single entity type (represented by entity counts). If those are true, then we can reuse this.
	if len(pg.Caching.EntityCounts) == 1 &&
		len(pg.Filters) == 1 &&
		pg.Filters[0].Type == "timestamp" &&
		len(pg.Filters[0].Values) == 2 {
		s, _ := strconv.Atoi(pg.Filters[0].Values[0])
		e, _ := strconv.Atoi(pg.Filters[0].Values[1])
		start := configstore.Timestamp(s)
		end := configstore.Timestamp(e)
		if start > end {
			start, end = end, start
		}
		creation := configstore.Timestamp(pg.Timestamp)
		counts := convertToConfigStoreEntityCount(pg.Caching.EntityCounts)
		globals.BackendTransientConfig.POSTResponseRepo.Add(foldername, configstore.Timestamp(dbReadStartLoc), end, creation, &counts) // not start, but dbReadStartLoc. Because start is the start of the entire response, not the container we just generated. This is related to the container that we generated, so we use the dbReadStartLoc.
