chakracore-rs
This is a wrapper around the JavaScript Runtime (JSRT), used in Microsoft Edge and node-chakracore. The library is still in pre-release and is not yet stable. The tests try to cover as much functionality as possible but memory leaks and segfaults may occur. If you want a more stable library, use the underlying API directly: chakracore-sys.

Add this to your Cargo.toml
:
toml
[dependencies]
chakracore = "0.1.0"
... and this to your crate root:
rust
extern crate chakracore as js;
This library, by itself is simple and easily installed, but its
chakracore-sys
dependency is not. To ensure a successful build, please view
the chakracore-sys
build
instructions.
```rust extern crate chakracore as js;
fn main() { let runtime = js::Runtime::new().unwrap(); let context = js::Context::new(&runtime).unwrap(); let guard = context.make_current().unwrap();
let result = js::script::eval(&guard, "(5 + 5)").unwrap(); asserteq!(result.tointeger(&guard), 10); } ```
```rust extern crate chakracore as js;
fn main() { let runtime = js::Runtime::new().unwrap(); let context = js::Context::new(&runtime).unwrap(); let guard = context.make_current().unwrap();
let multiply = js::value::Function::new(&guard, Box::new(|guard, info| { let result = info.arguments[0].tointeger(guard) * info.arguments[1].tointeger(guard); Ok(js::value::Number::new(guard, result).into()) }));
let result = multiply.call(&guard, &[ &js::value::Number::new(&guard, 191).into(), &js::value::Number::new(&guard, 7).into(), ]).unwrap();
asserteq!(result.tointeger(&guard), 1337); } ```
