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: exchange_info_service.go
    path of file: ./repos/go-binance/v2
    
    the code of the file until where you have to start completion: package binance

import (
	"context"
	"net/http"

	"github.com/adshao/go-binance/v2/common"
)

// ExchangeInfoService exchange info service
type ExchangeInfoService struct {
	c           *Client
	symbol      string
	symbols     []string
	permissions []string
}

// Symbol set symbol
func (s *ExchangeInfoService) Symbol(sy
    
func (s *Symbol) MaxNumOrdersFilter() *MaxNumOrdersFilter {
	for _, filter := range s.Filters {
		if filter["filterType"].(string) == string(SymbolFilterTypeMaxNumOrders) {
			f := &MaxNumOrdersFilter{}
			if i, ok := filter["maxNumOrders"]; ok {
				if mno, okk := common.ToInt(i); okk == nil {
					f.MaxNumOrders = mno
				}
			}
			return f
		}
	}
	return nil
}
