From 6764e6e8ac3f1223536c35d7daef0755df144643 Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Tue, 5 Sep 2023 15:26:37 +0100 Subject: examples/rust: Slightly simplify hello-world There is no need in this case to declare REQUEST_BUF as a global variable. Declaring it local to uwr_request_handler() lets us get rid of the unsafe code blocks.
