我在 gitlab runner 上使用 docker executor 作为我正在使用的图像，但docker:stable 收到此错误：

$ docker login gitlab.mydomain.com:5050 -u myusername-p mytoken

这是我的config.toml

concurrent = 1
check_interval = 0

  session_timeout = 1800

    "[rust]": {

        "editor.formatOnSave": true

我在 vscode 中有这些 Rust 设置。它们对于格式化效果很好，但行长比我想要的要短。有没有办法调整最大线长度？

为什么这个程序这么慢？我认为代码已经相当优化，但在我的根文件系统上使用时，它比 find 命令花费的时间要长得多。

它大约需要 4 分钟，而 find 命令大约需要 40 秒。

我尝试删除排序算法，但并没有加快程序速度。

package main

import (
    "fmt"
    "io"
    "io/fs"
    "log"
    "os"
    "sort"
    "sync"

)

var (
    mountpoint = kingpin.Flag("mount", "The mount to find the largest file usages. Can be a subath of mount").Required().String()
    limit      = kingpin.Flag("limit", "The maximum number of files return to the display").Default("10").Short('l').Int()
)
var device string

我正在尝试使用呈现 html 的 Exchangelib 发送电子邮件。

下面是我的电子邮件功能和正文

def send_email(account, subject, body, recipients):
    """
    >>> send_email(account, 'Subject line', 'Hello!', ['info@example.com'])
    """
    to_recipients = []
    for recipient in recipients:
        to_recipients.append(Mailbox(email_address=recipient))
    # Create message
    m = Message(account=account,
                folder=account.sent,
                subject=subject,
                body=body,
                to_recipients=to_recipients)

在 python 中，如果我有一个像 [2, 4, 6] 这样的数组，我可以执行以下操作

old_arr = [2, 4, 6]
new_arr = [x*2 for x in old_arr]

rust 中是否有类似的属性可以让我在返回数组之前修改它？
