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.
requires writable_semialphabet< alphabet_type > auto const rank_to
A view over an alphabet, given a range of ranks.
Definition: rank_to.hpp:66
constexpr auto assign_rank_to
Assign a rank to an alphabet object.
Definition: alphabet/concept.hpp:293
requires requires

Definition: alphabet/concept.hpp:164
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
A refinement of seqan3::semialphabet that adds assignability.
The SeqAn namespace for views.
