Caches the most recent element within the view so that dereferencing the view's iterator multiple times doesn't incur any recomputation. This can be useful in adaptor pipelines that include combinations of view::filter and view::transform , for instance. More... | |

Caches the most recent element within the view so that dereferencing the view's iterator multiple times doesn't incur any recomputation. This can be useful in adaptor pipelines that include combinations of view::filter
and view::transform
, for instance.
views::cache1
is always single-pass.
