Dune::Std Namespace Reference
Namespace for features backported from new C++ standards. More...
Classes | |
class | default_accessor |
A type for indexed access to elements of mdspan. More... | |
class | extents |
Multidimensional index space with dynamic and static extents. More... | |
struct | identity |
A function object type whose operator() returns its argument unchanged. More... | |
struct | layout_left |
A layout where the leftmost extent has stride 1. More... | |
struct | layout_right |
A layout where the rightmost extent has stride 1, and strides increase right-to-left as the product of extents. More... | |
struct | layout_stride |
A layout mapping where the strides are user-defined. More... | |
class | mdarray |
An owning multi-dimensional array analog of mdspan. More... | |
class | mdspan |
A multi-dimensional non-owning array view. More... | |
struct | nonesuch |
Type representing a lookup failure by std::detected_or and friends. More... | |
class | span |
A contiguous sequence of elements with static or dynamic extent. More... | |
Typedefs | |
template<class IndexType , std::size_t R> | |
using | dextents = typename Impl::DExtentsImpl< IndexType, std::make_integer_sequence< std::size_t, R > >::type |
Alias of extents of given rank R and purely dynamic extents. See [mdspan.extents.dextents]. | |
template<typename Default , template< typename... > class Op, typename... Args> | |
using | detected_or = Impl::detector< Default, void, Op, Args... > |
Detects whether Op<Args...> is valid and makes the result available. More... | |
template<template< typename... > class Op, typename... Args> | |
using | is_detected = typename detected_or< nonesuch, Op, Args... >::value_t |
Detects whether Op<Args...> is valid. More... | |
template<template< typename... > class Op, typename... Args> | |
using | detected_t = typename detected_or< nonesuch, Op, Args... >::type |
Returns Op<Args...> if that is valid; otherwise returns nonesuch. More... | |
template<typename Default , template< typename... > class Op, typename... Args> | |
using | detected_or_t = typename detected_or< Default, Op, Args... >::type |
Returns Op<Args...> if that is valid; otherwise returns the fallback type Default . More... | |
template<typename Expected , template< typename... > class Op, typename... Args> | |
using | is_detected_exact = std::is_same< Expected, detected_t< Op, Args... > > |
Checks whether Op<Args...> is Expected without causing an error if Op<Args...> is invalid. More... | |
template<typename Target , template< typename... > class Op, typename... Args> | |
using | is_detected_convertible = std::is_convertible< Target, detected_t< Op, Args... > > |
Checks whether Op<Args...> is convertible to Target without causing an error if Op<Args...> is invalid. More... | |
Functions | |
template<class T > | |
constexpr auto | to_address (T &&p) noexcept |
Obtain the address represented by p without forming a reference to the object pointed to by p . | |
Variables | |
constexpr std::size_t | dynamic_extent = std::numeric_limits<std::size_t>::max() |
A constant of type std::size_t that is used to differentiate std::span of static and dynamic extent. | |
Detailed Description
Namespace for features backported from new C++ standards.
The namespace Dune::Std contains library features of new C++ standards and technical specifications backported to older compilers. Most features are detected and pulled into this namespace from the standard library if your compiler has native support. If it doesn't, we provide a fallback implementation on a best-effort basis.
