Compile-time including of directories.

This crate works in a similar fashion as the include_bytes! macro in Rust, except it includes a whole directory and stores them in a perfect hash function map from the phf crate.

All pathnames in the directory processed by the include_dir! macro must be valid UTF-8.

Usage

[dependencies]
incdir = "0.1.0"
phf = { version = "*", features = ["macros"] }

#![feature(proc_macro_hygiene)]
use phf::Map;

static TEXTURES: Map<&'static str, &'static [u8]> = incdir::include_dir!("textures");

fn main() {
// The file is stored in "files/player.png", the directory prefix is stripped in the map.
let player = TEXTURES.get("player.png").unwrap();
// Stored in "textures/world/grass.png".
let grass = TEXTURES.get("world/grass.png").unwrap()
}
