Fix pin-project/METADATA Bug: 166324735 Test: make Change-Id: Ibe24c20ce6ca689e4032bcbbad9557f2010e7024
A crate for safe and ergonomic pin-projection.
Add this to your Cargo.toml:
[dependencies] pin-project = "0.4"
The current pin-project requires Rust 1.34 or later.
#[pin_project] attribute creates projection types covering all the fields of struct or enum.
use pin_project::pin_project; use std::pin::Pin; #[pin_project] struct Struct<T, U> { #[pin] pinned: T, unpinned: U, } impl<T, U> Struct<T, U> { fn method(self: Pin<&mut Self>) { let this = self.project(); let _: Pin<&mut T> = this.pinned; // Pinned reference to the field let _: &mut U = this.unpinned; // Normal reference to the field } }
code like this will be generated
