Required methods

#[must_use] unsafe fn build_alloc_ref(
    &mut self,
    ptr: NonNull<u8>,
    layout: Option<NonZeroLayout>
) -> Self::Ref

Safety

• ptr must denote a block of memory currently allocated via this allocator
• layout must fit that block of memory
• the alignment of the layout must match the alignment used to allocate that block of memory
