rust - include_bytes!() 可以用于自定义结构吗？

Question

我想在我的项目中嵌入一个图像文件。更准确地说，我想嵌入包含图像的已加载 Rust 对象，在我的例子中是 usvg::Tree。 , 或更高级的 cairo::ImageSurface .那可能吗？我只找到 String 的示例。

Answer 1

是的。

来自文档:

Includes a file as a reference to a byte array.

The file is located relative to the current file. (similarly to how modules are found)

This macro will yield an expression of type &'static [u8; N] which is the contents of the file.

数据类型没有限制。包括文字字节。值得一提的是，您需要确保字节对代码运行的平台有意义，并且您有某种解析字节的方法。
