1/// Reports in bytes how far the bump frontier of a `FixedBuffer` has moved. The2/// figure is the end index reached in the backing buffer, counting the payload3/// bytes and the alignment padding. Freeing or shrinking the most recent4/// allocation lowers it. The figure stands above the bytes that are live once5/// an allocation has been freed ahead of a later one, and once alignment gaps6/// remain behind.7pub fn used(owner: *const FixedBuffer) usize {8    return if (comptime observe.enabled)9        owner.inner.end_index10    else11        owner.end_index;12}
