form of escaping is context-dependent; Tornado’s templates are not aware of the syntax of HTML, JavaScript, etc, and so the template developer must sometimes explicitly apply the correct escaping function HTML body content (but not attribute values).

Ruby、Python 或 JavaScript，则可能不习惯将编译和运行分为两 个单独的步骤。Rust 是一种 预编译静态类型（ahead-of-time compiled）语言，这意味着你可 以编译程序，并将可执行文件送给其他人，他们甚至不需要安装 Rust 就可以运行。如果你给 他人一个 .rb、.py 或 .js 文件，他们需要先分别安装 Ruby，Python，JavaScript 实现（运行 时环 compile `branches` (bin "branches") due to 1 previous error 这个错误表明 Rust 期望一个 bool 却得到了一个整数。不像 Ruby 或 JavaScript 这样的语言， Rust 并不会尝试自动地将非布尔值转换为布尔值。必须总是显式地使用布尔值作为 if 的条 件。例如，如果想要 if 代码块只在一个数字不等于 0 时执行，可以把 if 表达式修改成下面 的地方都可能是一个 async 块或 async 函数中断并随后恢复的点。检 查一个 future 并查看其值是否已经准备就绪的过程被称为 轮询（polling）。 其它一些语言，例如 C# 和 JavaScript，也使用 async 和 await 关键字进行异步编程。如果你 熟悉这些语言，则可能会注意到它们与 Rust 的处理方式存在显著差异，包括语法层面。我们 将会看到，这样做是有充分理由的！
