error[E0277]: `PhantomPinned` cannot be unpinned
--> tests/ui/pin_project/overlapping_unpin_struct.rs:18:5
|
18 | is_unpin::<S<PhantomPinned>>(); //~ ERROR E0277
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ within `_::__S<'_, PhantomPinned>`, the trait `Unpin` is not implemented for `PhantomPinned`
|
= note: consider using `Box::pin`
note: required because it appears within the type `_::__S<'_, PhantomPinned>`
--> tests/ui/pin_project/overlapping_unpin_struct.rs:6:8
|
6 | struct S<T> {
| ^
note: required because of the requirements on the impl of `Unpin` for `S<PhantomPinned>`
--> tests/ui/pin_project/overlapping_unpin_struct.rs:5:1

6 | struct S<T> {
| ^^^^
note: required by a bound in `is_unpin`
--> tests/ui/pin_project/overlapping_unpin_struct.rs:15:16
|
15 | fn is_unpin<T: Unpin>() {}
| ^^^^^ required by this bound in `is_unpin`
= note: this error originates in the derive macro `::pin_project::__private::__PinProjectInternalDerive` (in Nightly builds, run with -Z macro-backtrace for more info)
