Struct sljs::runtime::Runtime

pub struct Runtime {
    pub heap: Heap,
    /* private fields */
}

The sljs JavaScript runtime.

It should be given a Parser implementation, e.g. NodejsParser or EsprimaParser:

use sljs::JSON;
use sljs::runtime::{Runtime, NodejsParser};

let parser = NodejsParser::new();
let mut sljs = Runtime::load(parser)
    .expect("Runtime::load");

The Runtime evaluates JavaScript source code and creates/stores crate::JSObjects.

sljs.evaluate("var x = 12")
    .expect("eval: var x");
let x = sljs.evaluate("x")
    .expect("eval: x");

assert_eq!(sljs.json_from(x), JSON::from(12.0));

Fields

heap: Heap
