通过pprof看到某个方法占用内存过大，大神们如何修改代码让内存占用更少？

pprof占用内存代码如下：  代码 func FirewallRulesGet() ([]FWRule, error) { rules := make([]FWRule, 1000) u, fwPolicy, err := firewallAPIInit() if err != nil { return rules, err } defer firewallAPIRelease(u, fwPolicy) ur, ep, enum, err := firewallRulesEnum(fwPolicy) if err != nil { return rules, err } defer firewallRulesEnumRealease(ur, ep) for itemRaw, length, err := enum.Next(1); length > 0; itemRaw, length, err = enum.Next(1) { if err != nil { return rules, fmt.Errorf("failed to seek next Rule item: %s", err) } rule, err := firewallRuleParams(itemRaw) if err != nil { return rules, err } rules = append(rules, rule) } return rules, nil }
