include_dir

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

Rendered Documentation:

• master
• Latest Release

Getting Started

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.

exmaple

use include_dir::{include_dir, Dir};

static PROJECT_DIR: Dir = include_dir!("$CARGO_MANIFEST_DIR");

fn main() {
    let lib_rs = PROJECT_DIR.get_file("src/lib.rs").unwrap();
    let body = lib_rs.contents_utf8().unwrap();
    assert!(body.contains("globs"));
    #[allow(unused_variables)]
    let glob: &str = "**";
    #[cfg(feature = "glob")]
    for entry in PROJECT_DIR.find(&glob).unwrap() {

        let file = PROJECT_DIR.get_file(format!("{}", entry.path().display()));
        if file.is_none() {
        } else {
            let file_contents = file.expect("REASON").contents_utf8();
            let file_path = file.expect("REASON").path();
            if file_contents.is_none() {
            } else {
                print!("{:}\n",file_path.display());
                print!("{:}",file_contents.clone().unwrap());
            }
        }
    }
}

sha2: display hash of file

use include_dir::{include_dir, Dir};
use sha2::{Digest, Sha256};

static PROJECT_DIR: Dir = include_dir!("$CARGO_MANIFEST_DIR");

fn main() {
    let lib_rs = PROJECT_DIR
        .get_file("src/bin/include_dir_example.rs")
        .unwrap();
    let body = lib_rs.contents_utf8().unwrap();
    assert!(body.contains("globs"));
    #[allow(unused_variables)]
    let glob: &str = "*dir_example*";
    #[cfg(feature = "glob")]
    for entry in PROJECT_DIR.find(&glob).unwrap() {
        let file = PROJECT_DIR.get_file(format!("{}", entry.path().display()));
        if file.is_none() {
        } else {
            let file_contents = file.expect("REASON").contents_utf8();
            let file_path = file.expect("REASON").path();
            if file_contents.is_none() {
            } else {
                let mut hasher = Sha256::new();
                hasher.update(file_contents.clone().unwrap());
                let hash = hasher.finalize();
                let hash_string = format!("{:x}", hash);
                print!("{:}\n", file_path.display());
                print!("{:}", file_contents.clone().unwrap());
                print!("{:}\n", hash_string);
            }
        }
    }
}

Features

• 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)
• File metadata (requires the metadata feature)

To-Do list:

• Compression?
