Bundle the source code of a rust cargo crate in a single source file.
Very useful for sending the source code to a competitive programming site that accept only a single file (codingame, I'm looking at you) and still keeping the cargo structure locally.
Add the following snippet to your Cargo.toml:
``` [package] (...) build = "build.rs"
[build-dependencies] rustsourcebundler = { git = "https://github.com/lpenz/rust-sourcebundler" } ```
And create the file build.rs with the following:
``` /*! Bundle mybin.rs and the crate libraries into singlefile.rs */
use std::path::Path; extern crate rustsourcebundler; use rustsourcebundler::Bundler;
fn main() {
let mut bundler: Bundler = Bundler::new(Path::new("src/bin/csbk.rs"),
Path::new("src/bin/singlefile.rs"));
bundler.crate_name("
