With --opt-level=3, this version runs in 0.014s on my machine, compared to 0.252s for the previous version. Mostly due to the #[inline] on get().

…ansch,oli-obk New lint: suggest `ptr::read` instead of `mem::replace(..., uninitialized())` resolves: rust-lang#5575 changelog: improvements to `MEM_REPLACE_WITH_UNINIT`: - add a new test case in `tests/ui/repl_uninit.rs` to cover the case of replacing with `mem::MaybeUninit::uninit().assume_init()`. - modify the existing `MEM_REPLACE_WITH_UNINIT` when replacing with `mem::uninitialized` to suggest using `ptr::read` instead. - lint with `MEM_REPLACE_WITH_UNINIT` when replacing with `mem::MaybeUninit::uninit().assume_init()`
