includedir

Travis Appveyor Crates.io version docs.rs Crates.io license

Include a directory in your Rust binary, e.g. static files for your web server or assets for your game.

Features

  • [x] Automatically compile data into binary
  • [x] Use rust-phf for efficient lookup
  • [x] Wrapping API around the phf map, to abstract away additional features
  • [x] Compression, with optional crate "flate2"
  • [x] Reading from source files for debug builds

Example

Cargo.toml

[package]
name = "example"
version = "0.1.0"

build = "build.rs"
include = ["data"]

[dependencies]
phf = "0.8.0"
includedir = "0.6.0"

[build-dependencies]
includedir_codegen = "0.6.0"

build.rs

extern crate includedir_codegen;

use includedir_codegen::Compression;

fn main() {
    includedir_codegen::start("FILES")
        .dir("data", Compression::Gzip)
        .build("data.rs")
        .unwrap();
}

src/main.rs

extern crate includedir;
extern crate phf;

use std::env;

include!(concat!(env!("OUT_DIR"), "/data.rs"));

fn main() {
    FILES.set_passthrough(env::var_os("PASSTHROUGH").is_some());

    println!("{:?}", FILES.get("data/foo"))
}
