邮件消息 — 对齐 PHP think\mail\Message

使用 Builder 模式构建邮件内容，通过 Mailer::send 发送。

PHP 对齐

// PHP think\facade\Mail
Mail::to('user@example.com')
    ->subject('Hello')
    ->html('<h1>Welcome</h1>')
    ->send();

Rust 用法

use sz_rust_core::mail::{MailMessage, MemoryMailer};

let msg = MailMessage::new()
    .to("user@example.com")
    .subject("Hello")
    .html("<h1>Welcome</h1>");

let mailer = MemoryMailer::new();
mailer.send(msg).unwrap();
