[][src]Crate web_static_pack


Embed static resources (GUI, assets, images, styles, html) within executable. Serve with hyper or any server of your choice.


Usage scenario:

  • Combines given directory tree into single, fast, binary-based single-file representation, called pack. Use simple CLI tool web-static-pack-packer to create a pack.
  • Pack could be embedded into your application using include_bytes! single macro.
  • Super-fast, zero-copy loader provides by-name access to files.
  • Easy-to-use hyper_loader allows super-quick integration with hyper-based server.


  • Super fast, low overhead
  • 100% 'static access, zero data copy
  • 100% pack-time calculated Content-Type, ETag (using sha3)
  • 100% pack-time calculated gzip-compressed files
  • Almost no external dependencies


  • By default all files with guesses text/ content type are treated as utf-8
  • Packs are not guaranteed to be portable across versions / architectures

Future goals:

  • You tell me


  • Directory listings
  • automatic index.html resolving
  • Uploads


  1. Create a pack from cargo doc:
$ cargo doc --no-deps
$ cargo run ./target/doc/ docs.pack
  1. Serve docs.pack from your web-application (see examples/docs)
use anyhow::{Context, Error};
use hyper::{
    service::{make_service_fn, service_fn},
    Body, Request, Response, Server,
use lazy_static::lazy_static;
use log::LevelFilter;
use simple_logger::SimpleLogger;
use std::{convert::Infallible, include_bytes, net::SocketAddr};
use web_static_pack::{hyper_loader::Responder, loader::Loader};

async fn main() -> () {

async fn service(request: Request<Body>) -> Result<Response<Body>, Infallible> {
    lazy_static! {
        static ref PACK: &'static [u8] = include_bytes!("docs.pack");
        static ref LOADER: Loader = Loader::new(&PACK).unwrap();
        static ref RESPONDER: Responder<'static> = Responder::new(&LOADER);


async fn main_result() -> Result<(), Error> {
    let address = SocketAddr::from(([0, 0, 0, 0], 8080));
    let server = Server::bind(&address).serve(make_service_fn(|_connection| async {
        Ok::<_, Infallible>(service_fn(service))

    log::info!("Server listening on {:?}", address);



Hyper integration. See examples/docs/main.rs for usage sample.


Main loader module. This is the part you should include in you target project if you want to read packs directly. After creating a pack with cli packer tool, include this into your program with include_bytes! macro. Then pass it to Loader::new(). Files may be retrieved using get() method.
