Every specialization of
layout_right_padded
is a
LayoutMappingPolicy
which provides a layout mapping that is similar to
layout_right::mapping
except that it has a
padding stride
.
Every specialization of
layout_right_padded
is
TriviallyCopyable
, and
std::
is_trivially_default_constructible_v
<
T

is
true
for any such specialization
T
.
Let
m
be the instance of the mapping type
layout_right_padded::mapping
. The padding stride of the mapping is the second to last stride
m.
