clingo-rs

Rust bindings to the clingo library. Clingo version 5.5.0.

Requirements

• a c++14 conforming compiler
  • at least gcc version 4.9
  • clang version 3.1 (using either libstdc++ provided by gcc 4.9 or libc++)

Per default the crate uses the clingo library via dynamic linking. It is assumed that a clingo dynamic library is installed on the system. You have to set the environment variable CLINGO_LIBRARY_PATH. For example:

export CLINGO_LIBRARY_PATH=/scratch/miniconda3/envs/test/lib

Features

Using derive macro

The crate provides a derive macro to help easing the use of rust data types as facts.

In your Cargo.toml add:

[dependencies]

clingo = { version = "0.7.2", features = ["derive"] }

In your source write:

use clingo::ToSymbol;
use clingo::ClingoError;
use clingo::FactBase;

#[derive(ToSymbol)]
struct MyPoint {
    x: i32,
    y: i32,
}

let p = MyPoint{ x:4, y:2 };
let fb = FactBase::new();
fb.insert(p);

The macro performs a conversion to snake case. This means the corresponing fact for MyPoint{x:4,y:2} is my_point(4,2).

Using static-linking

You can use the clingo library via static linking.

The recommended way to use the optional static linking support is as follows.

[dependencies]

clingo = { version = "0.7.2", features = ["static-linking"] }
