This is a backport of #162 and #170 to the smallvec 0.6 branch. To avoid bumping the minimum Rust version, the
maybe-uninit
crate is used in place ofstd::mem::MaybeUninit
. To avoid breaking changes, theArray::ptr
andptr_mut
methods are retained but are no longer used, and the API tofrom_buf_and_len_unchecked
is unchanged.
