Begin experimental support for pin reborrowing This commit adds basic support for reborrowing `Pin` types in argument position. At the moment it only supports reborrowing `Pin<&mut T>` as `Pin<&mut T>` by inserting a call to `Pin::as_mut()`, and only in argument position (not as the receiver in a method call). This PR makes the following example compile: ```rust #![feature(pin_ergonomics)] fn foo(_: Pin<&mut Foo>) { } fn bar(mut x: Pin<&mut Foo>) { foo(x); foo(x); } ``` Previously, you would have had to write `bar` as: ```rust fn bar(mut x: Pin<&mut Foo>) { foo(x.as_mut()); foo(x); } ``` Tracking: - #130494 r? `@compiler-errors` |
