Struct named_scope_entry

boost::log::attributes::named_scope_entry — The structure contains all information about a named scope.


// In header: <boost/log/attributes/named_scope.hpp>

struct named_scope_entry {
  enum scope_name_type;
  // construct/copy/destruct
  named_scope_entry(string_literal const &, string_literal const &, 
                    unsigned int, scope_name_type = general) noexcept;

  // public data members
  string_literal scope_name;
  string_literal file_name;
  unsigned int line;
  scope_name_type type;


The named scope entries are stored as elements of basic_named_scope_list container, which in turn can be acquired either from the basic_named_scope attribute value or from a thread-local instance.
