Crate drop_tracer

Simple memory leak detector.

The author of this crate is not good at English. Forgive me if the document is hard to read.

This crate has three main entry points.

• DropTracer::test_drop - For rough test. Panic if memory leak is detected.
• DropTracer::try_drop - For detail test. Receive error information if memory leak is detected.
• DropTracer::new - For manual control. On yourself, generate tracers and check the drop status.

Examples

let result = DropTracer::try_drop(|t| {
    let x = Chain::new(t.new_item());
    let y = Chain::new(t.new_item());
    x.borrow_mut().link = Some(y.clone());
    y.borrow_mut().link = Some(x.clone());
});

assert_eq!(result.unwrap_err().count(), 2);

struct Chain {
    link: Option<Rc<RefCell<Self>>>,
    _d: DropItem,
}

impl Chain {
    pub fn new(d: DropItem) -> Rc<RefCell<Self>> {
        let result = Self { link: None, _d: d };
        Rc::new(RefCell::new(result))
    }
}
