embd-rs

一个超级简单的文件和目录嵌入 Crates，在调试模式下从文件系统中加载文件，允许在不进行编译的情况下快速编辑和测试。

它也非常高效，在发布模式下将文件嵌入时不进行堆分配，利用 std::borrow::Cow。

在发布模式下，它回退到 include_str!、include_bytes! 和我们自己的自定义 include_dir!-like 实现。

用法

将其添加到您的 Cargo.toml 中

[dependencies]
embd = "0.1"

然后您可以像这样使用此 Crates

let contents: Cow<'_, str> = embd::string!("path/to/file.txt");
let bytes: Cow<'_, [u8]> = embd::bytes!("path/to/image.png");

let dir: embd::Dir = embd::dir!("path/to");
let files: Vec<embd::File> = dir.flatten();

请注意，您需要启用 procmacro2_semver_exempt cfg 选项才能使用此 Crates，您可以在项目根目录中的 .cargo/config.toml 中启用它，如下所示

[build]
rustflags = [ "--cfg", "procmacro2_semver_exempt" ]

待办事项

• 在调试模式下热重载文件。
• 不要依赖于 procmacro2_semver_exempt。
