mail::Header::plain — An unstructured, US-ASCII-only, E-mail header.
#include <libmail/headers.H>
mail::Header::plain plain_header("Content-Type", "text/plain");
std::cout << plain_header.toString();
This class creates an unstructured E-mail header. Two
arguments are provided to the constructor: the header's name,
and its contents. The header contents must contain only
US-ASCII characters. Use the
mail::Header::encoded(3x)
object to create a header containing non-US-ASCII content.
The toString() returns the
header as a single text string: “name: value”. Long
headers are folded at the nearest whitespace.
