Crate with make like functionality


#1

I often enough for cooperation with other language have to generate Rust source
code with help of rust-bindgen or rust_swig.

Because of cargo not cache include! (or I can not find switch for this?),
it takes time to rebuild such crate even if nothing was changed.

So to not depend on something like GNU Make, I wrote simple crate with functionality like this:

Make::new()
    .add_rule(Rule{
        input_file_paths: vec!["aa".into()],
        output_file_paths: vec!["b".into()],
        exec: Box::new(|input, output| { Ok(())})
    })
    .run().expect("make failed");

which run rule only if meta().modified() hint to do so.

It is really simple, so I wonder, may be crate with such functionality already exists?
