Nilstrieb	84b6049eb9	Use uninit checking from rustc ... rustc has proper heuristics for actually checking whether a type allows being left uninitialized (by asking CTFE). We can now use this for our helper instead of rolling our own bad version with false positives.	2023-03-21 18:28:06 +01:00
Alessandro Decina	49319b4206	uninit_vec: special case set_len(0) ... set_len(0) does not create uninitialized elements. Fixes a false positive with the following pattern: fn copy_slice_into_vec(dst: &mut Vec<u8>, src: &[u8]) { dst.reserve(src.len().saturating_sub(dst.len())); unsafe { dst.set_len(0); std::ptr::copy_nonoverlapping(src.as_ptr(), dst.as_mut_ptr(), src.len()); dst.set_len(src.len()); } }	2022-09-23 09:35:47 +01:00
