In C++23 we could do with a single overload that accepts cigar & assign_string(std::string_view const s) // not noexcept, should throw on problem
{
// implementation
}
template <std::ranges::contiguous_range rng_t>
requires (std::ranges::sized_range<rng_t> && std::same_as<char, std::ranges::range_value_t<rng_t>>)
cigar & assign_string(rng_t && s)
{
return assign_string(std::string_view{std::ranges::data(s), std::ranges::size(s)});
}I don't know why there should be an overload for |

| * In order to avoid unnecessary copies, you can initialise a seqan3::cigar from two char pointers that point to a | ||
| * contigous char array that stores the cigar string. | ||
| * | ||
| * \include test/snippet/alphabet/cigar/cigar_assign_string.cpp | ||
| * | ||
| * \attention If the cigar count cannot be correctly read, `0P` is added instead to the cigar string. | ||
| * Adding 0 padding is not impacting the alignment that the cigar string represents but | ||
| * keeps the number of cigar elements consistent with the input. | ||

needs an update (still refers to two char const *)

My use case is the following:
From an input file stream (a SAM file) I want to construct a
std::vector<seqan3::cigar>from a given cigar string e.g.3M. The current overloadseqan3::cigar::assign_string(seqan3::small_string s)would copy the string into asmall_stringbefore reading it and converting it to a respective letter ofseqan3::cigar. This is an unnecessary copy. We can avoid this by providing an overload withconst char *.
