Rust idiomatic bindings to the clingo library. Clingo version 5.6.2.

Per default the crate uses the clingo library via dynamic linking. It is assumed that a clingo dynamic library is installed on the system. While compile time the environment variable CLINGO_LIBRARY_PATH must be set. For example:

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

And for running the code that dynamically links to clingo make sure to have the clingo library in your LD_LIBRARY_PATH.

Have a look a at the clingo Readme for different ways of obtaining the binary releases of clingo.

You can also use the clingo library via static linking. The build system will attempt to compile clingo for static linking on your system. To build clingo for static linking you need the following tools installed:

• 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++)
  • at least MSVC 15.0 (Visual Studio 2017)
  • other compilers might work
• the cmake build system
  • at least version 3.18 is recommended
  • at least version 3.1 is required

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

[dependencies]
clingo = { version = "0.8.0", features = ["static-linking"] }

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

In your Cargo.toml add:

[dependencies]
clingo = { version = "0.8.0", features = ["derive"] }

In your source write:

use clingo::{ClingoError, FactBase, Symbol, ToSymbol};

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

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

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