embd-rs

一个超级简单的文件和目录嵌入 crate，在调试模式下从文件系统加载文件，允许快速编辑和测试循环，无需编译。

它也非常高效，在发布模式下嵌入文件时不进行堆分配，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! 类似实现。

使用方法

将此内容添加到您的 Cargo.toml

[dependencies]
embd = "0.1"

然后您可以像这样使用此 crate

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 crate，您可以通过在项目根目录的 .cargo/config.toml 中放入以下内容来启用它

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

待办事项

• 调试模式下文件的快速重新加载。
• 不要依赖 procmacro2_semver_exempt。
