This class acts as a compile time list of seqan3::field elements. It is used in specialising file classes to determine the elements in a seqan3::record.


#include <sstream>
auto input = R"(> TEST1
> Test2
> Test3
int main()
using seqan3::get;
// specify custom field combination/order to file:
auto record = fin.front(); // get current record, in this case the first
// record is tuple-like type, but allows access via field identifiers:
auto & id = get<seqan3::field::id>(record);
auto & seq = get<seqan3::field::seq>(record);
