/// ### What it does
/// Warns about fields in struct implementing `Send` that are neither `Send` nor `Copy`.
///
/// ### Why is this bad?
/// Sending the struct to another thread will transfer the ownership to
/// the new thread by dropping in the current thread during the transfer.
/// This causes soundness issues for non-`Send` fields, as they are also
/// dropped and might not be set up to handle this.
///
/// See:
/// * [*The Rustonomicon* about *Send and Sync*](https://doc.rust-lang.org/nomicon/send-and-sync.html)
/// * [The documentation of `Send`](https://doc.rust-lang.org/std/marker/trait.Send.html)
///
/// ### Known Problems
/// Data structures that contain raw pointers may cause false positives.
/// They are sometimes safe to be sent across threads but do not implement
/// the `Send` trait. This lint has a heuristic to filter out basic cases
/// such as `Vec<*const T>`, but it's not perfect. Feel free to create an
/// issue if you have a suggestion on how this heuristic can be improved.
///
/// ### Example
/// ```rust,ignore
/// struct ExampleStruct<T> {
/// rc_is_not_send: Rc<String>,
/// unbounded_generic_field: T,
/// }
///
/// // This impl is unsound because it allows sending `!Send` types through `ExampleStruct`
/// unsafe impl<T> Send for ExampleStruct<T> {}
/// ```
/// Use thread-safe types like [`std::sync::Arc`](https://doc.rust-lang.org/std/sync/struct.Arc.html)
/// or specify correct bounds on generic type parameters (`T: Send`).
