/// ### Example
|

///
|

/// ```rust

/// # #![deny(disjoint_capture_drop_reorder)]
|
||||
/// # #![allow(unused)]
|
||||
/// struct FancyInteger(i32);
|

/// fn drop(&mut self) {

/// }

///

///
|
||||
/// fn main() {

/// let p = Point { x: FancyInteger(10), y: FancyInteger(20) };

|
||||
///
|
||||
/// ### Explanation
|
||||
///
|
||||
/// In the above example `p.y` will be dropped at the end of `f` instead of with `c` if
|
||||
/// the feature `capture_disjoint_fields` is enabled.
