Getting Started

Add the following to your Cargo.toml.

[dependencies]
dl_api = "0.4"

Example

The code inside of the curly braces for link!() matches exactly with code inside of the curly braces for extern "C". This makes it easy for you to turn your extern "C"s into link!()s.

// Shared object: either "libmylibrary.so.1", "mylibrary-1.dll" or "libMyLibrary.dylib"
dl_api::link!(MyApi, "libmylibrary.so.1", {
    fn cFunction(param_name: ParamType) -> ReturnType;
});

fn main() {
    let api = MyApi::new().unwrap(); // unwrap the `Result`.

    let rtn: ReturnType = unsafe {
        (api.cFunction)(0);
    };
}

API

API documentation can be found on docs.rs.

Contribution

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.

Contributors are always welcome (thank you for being interested!), whether it be a bug report, bug fix, feature request, feature implementation or whatever. Don’t be shy about getting involved. I always make time to fix bugs, so usually a patched version of the library will be out a few days after a report. Features requests will not complete as fast. If you have any questions, design critques, or want me to find you something to work on based on your skill level, you can email me at jeronlau@plopgrizzly.com. Otherwise, here’s a link to the issues on GitHub. Before contributing, check out the contribution guidelines, and, as always, make sure to follow the code of conduct.
