Detailed Description

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

Note that you can assign 'U' as a character to dna15 and it will silently be converted to 'T'.

Like most alphabets, this alphabet cannot be initialised directly from its character representation. Instead initialise/assign from the character literal 'A'_dna15 or use the function seqan3::dna15::assign_char().

Constructor & Destructor Documentation

◆ dna15()

template<std::same_as< rna15 > t>
constexpr seqan3::dna15::dna15 ( t const &  r)
inlineconstexprnoexcept

Allow implicit construction from seqan3::rna15 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::dna15 and seqan3::rna15 are interchangeable as they behave nearly the same (e.g. same ranks, same char to rank conversion).

int main()
{
using namespace seqan3::literals;
seqan3::dna15 letter1 = 'C'_rna15; // implicitly converted
seqan3::dna15 letter2{};
letter2 = 'C'_rna15; // implicitly converted
}
Provides seqan3::rna15, container aliases and string literals.

seqan3::sequences (e.g. seqan3::dna15_vector) in general are not implicitly convertible and must be explicitly copied to be converted:

#include <vector>
int main()
{
using namespace seqan3::literals;
seqan3::dna15_vector vector{'A'_rna15, 'C'_rna15, 'G'_rna15}; // (element-wise) implicit conversion
// but this won't work:
// seqan3::dna15_vector dna15_vector{"ACGT"_rna15};
// as a workaround you can use:
// side note: this would also work without the implicit conversion.
seqan3::rna15_vector rna15_vector = "ACGT"_rna15;
seqan3::dna15_vector dna15_vector{rna15_vector.begin(), rna15_vector.end()};
}
std::vector< dna15 > dna15_vector
Alias for a std::vector of seqan3::dna15.
Definition dna15.hpp:163

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

#include <vector>
int main()
{
using namespace seqan3::literals;
seqan3::dna15_vector vector = "ACG"_dna15;
auto rna15_view = vector | seqan3::views::convert<seqan3::rna15>;
for (auto && chr : rna15_view) // converts lazily on-the-fly
{
static_assert(std::same_as<decltype(chr), seqan3::rna15 &&>);
}
}
The 15 letter RNA alphabet, containing all IUPAC smybols minus the gap.
Definition rna15.hpp:48
Provides seqan3::views::convert.

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

struct my_dna15 : public seqan3::dna15
{
// using seqan3::dna15::dna15; // uncomment to import implicit conversion shown by letter1
};
struct my_rna15 : public seqan3::rna15
{};
int main()
{
using namespace seqan3::literals;
// my_dna15 letter1 = 'C'_rna15; // NO automatic implicit conversion!
// seqan3::dna15 letter2 = my_rna15{}; // seqan3::dna15 only allows implicit conversion from seqan3::rna15!
}

This entity is stable. Since version 3.1.
