Quality alphabet concept.
Provides seqan3::alphabet_base.
A CRTP-base that makes defining a custom alphabet easier.
Definition: alphabet_base.hpp:57
constexpr rank_type to_rank() const noexcept
Return the letter's numeric value (rank in the alphabet).
Definition: alphabet_base.hpp:139
detail::min_viable_uint_t< size - 1 > rank_type
The type of the alphabet when represented as a number (e.g. via to_rank()).
Definition: alphabet_base.hpp:80
static constexpr detail::min_viable_uint_t< size > alphabet_size
The size of the alphabet, i.e. the number of different values it can take.
Definition: alphabet_base.hpp:203
std::conditional_t< std::same_as< char, void >, char, char > char_type
The char representation; conditional needed to make semi alphabet definitions legal.
Definition: alphabet_base.hpp:72
constexpr derived_type & assign_rank(rank_type const c) noexcept
Assign from a numeric value.
Definition: alphabet_base.hpp:191
A CRTP-base that refines seqan3::alphabet_base and is used by the quality alphabets.
Definition: phred_base.hpp:31
constexpr phred_type to_phred() const noexcept
Return the alphabet's value in Phred score representation.
Definition: phred_base.hpp:100
constexpr derived_type & assign_phred(phred_type const p) noexcept
Assign from the numeric Phred score value.
Definition: phred_base.hpp:125
int8_t phred_type
The integer representation of the quality score.
Definition: phred_base.hpp:40
constexpr auto to_phred
The public getter function for the Phred representation of a quality score.
Definition: concept.hpp:100
constexpr auto assign_phred_to
Assign a Phred score to a quality alphabet object.
Definition: concept.hpp:231
A concept that indicates whether an alphabet represents quality scores.
The main SeqAn3 namespace.
Definition: cigar_operation_table.hpp:2
SeqAn specific customisations in the standard namespace.
