Example code for reading an ArrayBufferView?

[DiThi]

Hi, despite the lack of documentation, examples or tests, I've figured out how to read most values I needed from function arguments. But I haven't been able to read an ArrayBuffer or ArrayBufferView.

Here's one of my attempts:

use v8::*;
fn testf(info: value::FunctionCallbackInfo) -> Result<Value, Value> {
    let arr = info.args[0].into_array_buffer_view().unwrap();
    println!("{:?}", arr);
    Ok(Value::from(value::undefined(&info.isolate)))
}

for which I get

29 |     let arr = info.args[0].into_array_buffer().unwrap();
   |               ^^^^^^^^^^^^ cannot move out of indexed content

let arr = &info.args[0]
let arr = arr.into_array_buffer().unwrap();
