Static Public Attributes | |
static constexpr detail::min_viable_uint_t< size > | alphabet_size |

Protected Types | |
Member types | |
using | char_type = std::conditional_t< std::same_as< char, void >, char, char > |
The char representation; conditional needed to make semi alphabet definitions legal. | |
using | rank_type = detail::min_viable_uint_t< size - 1 > |
The type of the alphabet when represented as a number (e.g. via to_rank()). | |
