error[E0277]: `PhantomPinned` cannot be unpinned
--> tests/ui/pin_project/overlapping_unpin_struct.rs:21:16
|
21 | is_unpin::<Foo<PhantomPinned>>(); //~ ERROR E0277
| ^^^^^^^^^^^^^^^^^^ within `_::__Origin<'_, PhantomPinned>`, the trait `Unpin` is not implemented for `PhantomPinned`, which is required by `Foo<PhantomPinned>: Unpin`
|
= note: consider using the `pin!` macro
consider using `Box::pin` if you need to access the pinned value outside of the current scope
note: required because it appears within the type `_::__Origin<'_, PhantomPinned>`

note: required for `Foo<PhantomPinned>` to implement `Unpin`

note: required by a bound in `is_unpin`

| ^^^^^ required by this bound in `is_unpin`
= note: this error originates in the macro `$crate::__pin_project_make_unpin_impl` which comes from the expansion of the macro `pin_project` (in Nightly builds, run with -Z macro-backtrace for more info)
