From 08d3f54928796557fc832467ad54f04908fc14e4 Mon Sep 17 00:00:00 2001 From: Wedson Almeida Filho Date: Wed, 27 Mar 2024 22:35:59 -0300 Subject: rust: alloc: introduce the `BoxExt` trait Make fallible versions of `new` and `new_uninit` methods available in `Box` even though it doesn't implement them because we build `alloc` with the `no_global_oom_handling` config. They also have an extra `flags` parameter that allows callers to pass flags to the allocator.
