Note: This release has been yanked. See #55 for details.

  • pin_project! macro now supports enums.

    To use pin_project! on enums, you need to name the projection type returned from the method.

    use pin_project_lite::pin_project;
use std::pin::Pin;

pin_project! {
    #[project = EnumProj]
    enum Enum<T, U> {
        Variant { #[pin] pinned: T, unpinned: U },
    }
}

impl<T, U> Enum<T, U> {
    fn method(self: Pin<&mut Self>) {
        match self.project() {
            EnumProj::Variant { pinned, unpinned } => {
                let _: Pin<&mut T> = pinned;
                let _: &mut U = unpinned;
            }
        }
    }
}

  • Support naming the projection types.

    By passing an attribute with the same name as the method, you can name the projection type returned from the method:

    use pin_project_lite::pin_project;
use std::pin::Pin;

pin_project! {
    #[project = StructProj]
    struct Struct<T> {
        #[pin]
        field: T,
    }
}

fn func<T>(x: Pin<&mut Struct<T>>) {
    let StructProj { field } = x.project();
    let _: Pin<&mut T> = field;
}
