Linus Torvalds on Rust support in kernel(lkml.org)

    I keep saying this, but the obvious fix is for the Linux kernel to use overcommit internally 
    just like they expect user space to do.

    impl<OkType, ErrorType> Result<OkType, ErrorType> {
        fn unwrap(self) -> OkType {
            if Ok(x) = self {
                return x;
            }
            panic!("not ok");
        }
    }

    fn my_fn() -> Result<(), Error> {
        // if this failed, returns some Err()
        let my_x = my_struct.do_something_that_can_fail()?;
        // ditto
        let my_y = my_x.something_else_that_can_fail()?;
        // no failures? Ok
        Ok(my_y)
    }

    fn my_fn() -> Result<(), Error> {
        // Equivalent
        Ok(my_struct.do_something_that_can_fail()?
                    .something_else_that_can_fail()?)
    }

  my_struct.do_something()?
    .get_this()?
    .get_that()?
    .as_ref()
    .as_paper_airplane()?;
