任何人都可以告诉我为什么编译时我写的下面的代码一直在抱怨istream_iterator is not a member of std请你告诉我吗？多谢你们

#include <cstdlib>
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string.h>
#include <vector>
#include <fstream>
//#include<sstream>

struct field_reader: std::ctype<char> {

    field_reader(): std::ctype<char>(get_table()) {}

    static std::ctype_base::mask const* get_table() {
        static std::vector<std::ctype_base::mask>
            rc(table_size, std::ctype_base::mask());

        rc[';'] = std::ctype_base::space;
        return &rc[0];
    }
};


struct Stud{
    double VehicleID;
    double FinancialYear;
    double VehicleType;
    double Manufacturer;
    double ConditionScore;


    friend std::istream &operator>>(std::istream &is, Stud &s) {
        return is >> s.VehicleID >> s.FinancialYear >> s.VehicleType >>      s.Manufacturer >> s.ConditionScore;
    }

    // …

我的代码返回错误

expected item, found `let`

那是什么意思？

pub struct MyStorage{
    name: Vec<u8>
}

impl Storage for MyStorage {
   //let mut name: Vec<u8> = [0x11];
   fn get(&mut self) -> Vec<u8> {
       self.name
       }
   }

let my_storage = MyStorage{name = [0x11]};
