Core alphabet concept and free function/type trait wrappers.
A wrapper type around an existing view adaptor that enables "deep view" behaviour for that view.
Definition: deep.hpp:104
Provides seqan3::views::deep.
auto const to_char
A view that calls seqan3::to_char() on each element in the input range.
Definition: to_char.hpp:63
constexpr auto to_char
Return the char representation of an alphabet object.
Definition: alphabet/concept.hpp:386
decltype(detail::transform< trait_t >(list_t{})) transform
Apply a transformation trait to every type in the list and return a seqan3::type_list of the results.
Definition: type_list/traits.hpp:469
The generic alphabet concept that covers most data types used in ranges.
The SeqAn namespace for views.
Definition: char_strictly_to.hpp:22
The <ranges> header from C++20's standard library.
