wll-rs

Wolfram LibraryLink interface for Rust

Inspired by wll-interface.

Purpose:

// lib.rs
use wll::{Error, ErrorKind, Result};

#[wll::setup]
fn setup() {}

#[wll::teardown]
fn teardown() {}

// export function named `wll_add_two`
#[wll::export]
fn add_two(a: isize, b: isize)->Result<isize> {
    a.checked_add(b)
     .ok_or_else(|| Error::from(ErrorKind::NumericalError))
}

#[wll::export(factorial)]
fn fac(n: usize) -> Result<usize> {
    Ok(if n == 0 { 1 } else { n * fac(n - 1)? })
}
