A super simple file and directory embedding crate, that loads files from the filesystem on debug mode, allowing for quick edit-and-test cycles without compilation.
It is also super efficient, and does not heap allocate when the
files are embedded on release mode by utilizing std::borrow::Cow.
On release mode it falls back to include_str!, include_bytes!
and our own custom include_dir!-like implementation.
Add this to your Cargo.toml:
[dependencies]
embd = "0.1"Then you can use this crate like so:
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();Note that you will need to enable the procmacro2_semver_exempt cfg
option to use this crate, you can enable it like so, by putting this in
.cargo/config.toml in the project root:
[build]
rustflags = [ "--cfg", "procmacro2_semver_exempt" ]- Hot reloading of files in debug mode.
- Don't depend on
procmacro2_semver_exempt.
