Macro rhai::def_package

macro_rules! def_package {
    ($root:ident : $package:ident : $comment:expr , $lib:ident , $block:stmt) => { ... };
}

Macro that makes it easy to define a package (which is basically a shared module) and register functions into it.

Functions can be added to the package using Module::set_native_fn.

Example

Define a package named MyPackage with a single function named my_add:

use rhai::{Dynamic, EvalAltResult};
use rhai::def_package;

fn add(x: i64, y: i64) -> Result<i64, Box<EvalAltResult>> { Ok(x + y) }

def_package!(rhai:MyPackage:"My super-duper package", lib,
{
    // Load a binary function with all value parameters.
    lib.set_native_fn("my_add", add);
});
