Type list traits (return a single type) | |
template<ptrdiff_t idx, typename list_t > | |
using | at = typename decltype(detail::at< idx >(list_t{}))::type |
Return the type at given index from the type list. | |
template<typename list_t > | |
using | front = typename decltype(detail::front(list_t{}))::type |
Return the first type from the type list. | |
template<typename list_t > | |
using | back = typename decltype(detail::back(list_t{}))::type |
Return the last type from the type list. | |
Type list traits (return a type list) | |

using | concat = decltype(detail::concat(lists_t{}...)) |
Join two seqan3::type_list s into one. | |
template<typename list_t > | |
using | drop_front = decltype(detail::drop_front(list_t{})) |

template<ptrdiff_t i, typename list_t > | |
using | take = typename decltype(detail::split_after< i >(list_t{}))::first_type |
Return a seqan3::type_list of the first n types in the input type list. | |

template<ptrdiff_t i, typename list_t > | |
using | take_last = drop< size< list_t > - i, list_t > |
Return a seqan3::type_list of the last n types in the input type list. | |
template<ptrdiff_t i, typename list_t > | |
using | drop_last = take< size< list_t > - i, list_t > |
Return a seqan3::type_list of the types the input type list, except the last n . | |
template<ptrdiff_t i, typename list_t > | |
using | split_after = decltype(detail::split_after< i >(list_t{})) |
Split a seqan3::type_list into two parts returned as a pair of seqan3::type_list. | |
template<template< typename > typename trait_t, typename list_t > | |
using | transform = decltype(detail::transform< trait_t >(list_t{})) |
Apply a transformation trait to every type in the list and return a seqan3::type_list of the results. | |
template<typename replace_t , std::ptrdiff_t i, typename list_t > | |
using | replace_at = decltype(detail::replace_at< replace_t, i >(list_t{})) |

template<typename query_t , typename list_t > | |
constexpr bool | contains = (find<query_t, list_t> != -1) |
