M E T A C A L L

A library for providing inter-language foreign function interface calls

Abstract

METACALL is a library that allows calling functions, methods or procedures between programming languages. With METACALL you can transparently execute code from / to any programming language, for example, call TypeScript code from Rust.

Install

MetaCall is a C plugin based library. This crate wraps the C library into Rust, so in order to make it work, you should install MetaCall binaries first (click here for additional info about the install script): sh bash <(curl -sL https://raw.githubusercontent.com/metacall/install/master/install.sh)

Example

sum.ts javascript export function sum(a: number, b: number): number { return a + b; }

main.rs ``` rust fn main() { let _d = defer(metacall::destroy);

match metacall::initialize() {
    Err(e) => {
        println!("{}", e);
        panic!();
    }
    _ => println!("MetaCall initialized"),
}

let scripts = ["sum.ts".to_string()];

if let Err(e) = metacall::load_from_file("ts", &scripts) {
    println!("{}", e);
    panic!();
}

match metacall::metacall(
    "sum",
    &[metacall::Any::Double(1.0), metacall::Any::Double(2.0)],
) {
    Err(e) => {
        println!("{}", e);
        panic!();
    }
    Ok(ret) => {
        println!("{:?}", ret);
    }
}

} ```
