An evolution of the include_str!() and include_bytes!() macros for embedding an entire directory tree into your binary.

Rendered Documentation:

• master
• Latest Release

The include_dir!() macro works very similarly to the normal include_str!() and include_bytes!() macros. You pass the macro a file path and assign the returned value to some static variable.

Most importantly, the file path must be relative to the project root as indicated by the CARGO_MANIFEST_DIR environment variable.

#[macro_use]
extern crate include_dir;

use include_dir::Dir;
use std::path::Path;

static PROJECT_DIR: Dir = include_dir!(".");

// of course, you can retrieve a file by its full path
let lib_rs = PROJECT_DIR.get_file("src/lib.rs").unwrap();

// you can also inspect the file's contents
let body = lib_rs.contents_utf8().unwrap();
assert!(body.contains("SOME_INTERESTING_STRING"));

// you can search for files (and directories) using glob patterns
#[cfg(feature = "search")]
{
    let glob = "**/*.rs";
    for entry in PROJECT_DIR.find(glob).unwrap() {
        println!("Found {}", entry.path().display());
    }
}

• Embed a directory tree into your binary at compile time
• Find a file in the embedded directory
• Search for files using a glob pattern (requires the globs feature)

To-Do list:

• File metadata
• Compression?
