Crate deno_runner
source ·Expand description
Javascript runner in Rust
This runner using deno_core with additional helper function to run Javascript inside Rust. You can also binding the Rust functions into Javascript.
Usage
Add this crate to your Cargo.toml
[dependencies]
deno_runner = { git = "https://github.com/fossil-engineering/deno-runner-rs" }
Example
Basic usage
use deno_runner::Builder;
use std::collections::HashMap;
#[tokio::main]
async fn main() {
let code = r#"
const add = (a, b) => a + b;
add(a, b)
"#;
let runner = Builder::new().build();
let vars = HashMap::from([("a", 1), ("b", 2)]);
let result = runner.run(code, Some(vars)).await.unwrap();
assert_eq!(result, "3");
}Calling Rust functions from Javascript
use deno_runner::{anyhow::Result, op, Builder};
use std::collections::HashMap;
#[op]
fn add(a: i32, b: i32) -> i32 {
a + b
}
#[tokio::main]
async fn main() {
let code = "add(a, b)";
let runner = Builder::new().add_op(add::decl()).build();
let vars = HashMap::from([("a", 1), ("b", 2)]);
let result = runner.run(code, Some(vars)).await.unwrap();
assert_eq!(result, "3");
