From cfda050c01bba4a9b2ca9356b317ba22d6da0ca7 Mon Sep 17 00:00:00 2001 From: Cerberuser Date: Sun, 13 Oct 2019 18:48:07 +0700 Subject: [PATCH] Add `dyn` to `Any` documentation I noticed that in documentation to `Any` trait the old trait object syntax is used, which could be confusing for newcomers, since we generally recommend using `dyn Trait` instead of just `Trait`. This PR changes the documentation comment, so that it uses `&dyn Any`, `&mut dyn Any` and `Box`, correspondingly. --- src/libcore/any.rs | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/src/libcore/any.rs b/src/libcore/any.rs index 85b59162620fa..ba0b067969679 100644 --- a/src/libcore/any.rs +++ b/src/libcore/any.rs @@ -2,14 +2,14 @@ //! of any `'static` type through runtime reflection. //! //! `Any` itself can be used to get a `TypeId`, and has more features when used -//! as a trait object.
