Detailed Description

The 15 letter RNA alphabet, containing all IUPAC smybols minus the gap.

This alphabet has the same internal representation as seqan3::dna15, the only difference is that it prints 'U' on character conversion instead of 'T'. You can assign between values of seqan3::dna15 and seqan3::rna15.

Like most alphabets, this alphabet cannot be initialised directly from its character representation. Instead initialise/assign from the character literal 'A'_rna15 or use the function seqan3::rna15::assign_char().

Constructor & Destructor Documentation

rna15()

template<std::same_as< dna15 > t>

constexpr seqan3::rna15::rna15 ( t const &  r )

inlineconstexprnoexcept

Allow implicit construction from seqan3::dna15 of the same size.

Normally, we do not allow implicit conversion of single argument constructors, but in this case we make an exception, because seqan3::rna15 and seqan3::dna15 are interchangeable as they behave nearly the same (e.g. same ranks, same char to rank conversion).

#include <seqan3/alphabet/nucleotide/dna15.hpp>
#include <seqan3/alphabet/nucleotide/rna15.hpp>
 
int main()
{
    using namespace seqan3::literals;
 
    seqan3::rna15 letter1 = 'C'_dna15; // implicitly converted
    seqan3::rna15 letter2{};
    letter2 = 'C'_dna15; // implicitly converted
}

seqan3::sequences (e.g. seqan3::rna15_vector) in general are not implicitly convertible and must be explicitly copied to be converted:

#include <vector>
 
#include <seqan3/alphabet/nucleotide/dna15.hpp>
#include <seqan3/alphabet/nucleotide/rna15.hpp>
 
int main()
{
    using namespace seqan3::literals;
 
    seqan3::rna15_vector vector{'A'_dna15, 'C'_dna15, 'G'_dna15}; // (element-wise) implicit conversion
 
    // but this won't work:
    // seqan3::rna15_vector rna15_vector{"ACGT"_dna15};
 
    // as a workaround you can use:
    // side note: this would also work without the implicit conversion.
    seqan3::dna15_vector dna15_vector = "ACGT"_dna15;
    seqan3::rna15_vector rna15_vector{dna15_vector.begin(), dna15_vector.end()};
}

You can avoid this copy by using std::ranges::views:

#include <vector>
 
#include <seqan3/alphabet/nucleotide/dna15.hpp>
#include <seqan3/alphabet/nucleotide/rna15.hpp>
#include <seqan3/utility/views/convert.hpp>
 
int main()
{
    using namespace seqan3::literals;
 
    seqan3::rna15_vector vector = "ACG"_rna15;
 
    auto dna15_view = vector | seqan3::views::convert<seqan3::dna15>;
 
    for (auto && chr : dna15_view) // converts lazily on-the-fly
    {
        static_assert(std::same_as<decltype(chr), seqan3::dna15 &&>);
    }
}

This conversion constructor only allows converting seqan3::dna15 to seqan3::rna15. Other alphabets that inherit from seqan3::dna15 will not be implicitly convertible to seqan3::rna15.

#include <seqan3/alphabet/nucleotide/dna15.hpp>
#include <seqan3/alphabet/nucleotide/rna15.hpp>
 
struct my_rna15 : public seqan3::rna15
{
    // using seqan3::rna15::rna15; // uncomment to import implicit conversion shown by letter1
};
 
struct my_dna15 : public seqan3::dna15
{};
 
int main()
{
    using namespace seqan3::literals;
 
    // my_rna15 letter1 = 'C'_dna15; // NO automatic implicit conversion!
    // seqan3::rna15 letter2 = my_dna15{}; // seqan3::rna15 only allows implicit conversion from seqan3::dna15!
}

This entity is stable. Since version 3.1.
