	Prints the elements of a sequence to an output stream.

Detailed Description

template<typename rng_t>
requires std::ranges::input_range<rng_t> && nonrecursive_range<rng_t>
struct seqan3::input_range_printer< rng_t >

A printer for arbitrary input ranges.

All input ranges can be printed to the seqan3::debug_stream element-wise (if their elements are printable). If the element type models seqan3::alphabet (and is not an unsigned integer), the range is printed just as if it were a string, i.e. std::vector<dna4>{'C'_dna4, 'G'_dna4, 'A'_dna4} is printed as "CGA".

In all other cases the elements are comma separated and the range is enclosed in brackets, i.e. std::vector<int>{3, 1, 33, 7} is printed as "[3,1,33,7]".

This printer excludes recursive ranges, such as entities from the std::filesystem library.

Template Parameters

rng_t Type of the range to be printed; must model std::ranges::input_range and be non-recursive.
