From 5c1ebf902bad2ed8058b57deaca9645de1286eca Mon Sep 17 00:00:00 2001 From: Andrew Gallant Date: Mon, 16 Jun 2025 10:05:56 -0400 Subject: [PATCH] Add `rustfmt.toml` (#14072) We've gotten away without this file for a while. In particular, we explicitly use its default settings. However, this is occasionally problematic in certain contexts where `rustfmt` is invoked directly. Or in contexts where the Rust Edition is otherwise not specified. At least, this happens when using the Rust vim plugin. When an edition isn't explicitly specified, it defaults back to the 2015 edition. I think that there aren't a lot of rustfmt changes, and so we've been able to get away with this for a while. But it looks like something in the 2024 edition changes how imports are ordered. So to make it explicit that we want to use the 2024 edition of rustfmt, we opt into it. This is analogous to a change made to the Ruff repository somewhat recently: https://github.com/astral-sh/ruff/pull/18197 --- rustfmt.toml | 2 ++ 1 file changed, 2 insertions(+) create mode 100644 rustfmt.toml diff --git a/rustfmt.toml b/rustfmt.toml new file mode 100644 index 000000000..f3e454b61 --- /dev/null +++ b/rustfmt.toml @@ -0,0 +1,2 @@ +edition = "2024" +style_edition = "2024"
