A library for providing inter-language foreign function interface calls
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.
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 installing it on other platforms):
sh
curl -sL https://raw.githubusercontent.com/metacall/install/master/install.sh | sh
sum.ts
javascript
export function sum(a: number, b: number): number {
return a + b;
}
main.rs
``` rust
use metacall::{switch, metacall, loaders};
fn main() { // Initialize Metacall at the top let _metacall = switch::initialize().unwrap();
// Load the file
loaders::from_single_file("ts", "sum.ts").unwrap();
// Call the sum function
let sum = metacall::<f64>("sum", [1.0, 2.0]).unwrap();
assert_eq!(sum, 3.0);
} ```
