enum Enum<T> {
Variant(#[pin] T)
}

## [0.4.17] - 2020-05-18
**Note:** This release has been yanked because it [failed to compile with syn 1.0.84 and later](https://github.com/taiki-e/pin-project/pull/335).
- [Support naming the projection types.](https://github.com/taiki-e/pin-project/pull/202)

enum Enum<T> {
Variant(#[pin] T),
}
fn func<T>(x: Pin<&mut Enum<T>>) {
match x.project() {

```rust
#[pin_project(!Unpin)]
struct Struct<T, U> {
field: T,
}
```
This is equivalent to use `#[pin]` attribute for `PhantomPinned` field.
```rust
#[pin_project]
struct Struct<T, U> {
field: T,
#[pin] // Note that using `PhantomPinned` without `#[pin]` attribute has no effect.
_pin: PhantomPinned,
}
```

```rust
#[pinned_drop]
impl<T> PinnedDrop for Foo<'_, T> {
fn drop(mut self: Pin<&mut Self>) {
**self.project().was_dropped = true;
}
}
```

```rust
fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut T> {
self.project_into().pinned
}
```
- [Prevent `UnpinStruct` from appearing in the document by default.](https://github.com/taiki-e/pin-project/pull/71) See [#71](https://github.com/taiki-e/pin-project/pull/71) for more details.
## [0.4.0-alpha.8] - 2019-09-03
- [Improve document of generated code.](https://github.com/taiki-e/pin-project/pull/62). Also added an option to control the document of generated code. See [#62](https://github.com/taiki-e/pin-project/pull/62) for more details.

- [Suppress `dead_code` lint in generated types.](https://github.com/taiki-e/pin-project/pull/57)
## [0.4.0-alpha.6] - 2019-09-01
- [Allow using `#[pin_project]` type with private field types](https://github.com/taiki-e/pin-project/pull/53)
## [0.4.0-alpha.5] - 2019-08-24
- [`#[project]` attribute now supports `match` expressions at the position of the initializer expression of `let` expressions.](https://github.com/taiki-e/pin-project/pull/51)

- [`#[project]` attribute can now be used for impl blocks.](https://github.com/taiki-e/pin-project/pull/46)
- [`#[pin_project]` attribute can now detect that the type used does not have its own drop implementation without actually implementing drop.](https://github.com/taiki-e/pin-project/pull/48) This removed some restrictions.
## [0.4.0-alpha.2] - 2019-08-13
- Update `proc-macro2`, `syn`, and `quote` to 1.0.
## [0.4.0-alpha.1] - 2019-08-11
