A query parameter.
Defined in header <boost/url/param.hpp>
struct param
Objects of this type represent a single key and value pair in a query string
where a key is always present and may be empty, while the presence of a value
is indicated by has_value equal to true. An empty
value is distinct from no value. Depending on where the object was obtained,
the strings may or may not contain percent escapes. For most usages, key
comparisons are case-sensitive and duplicate keys in a query are possible.
However, it is the authority that has final control over how the query is
interpreted.
query-params = query-param *( "&" query-param ) query-param = key [ "=" value ] key = *qpchar value = *( qpchar / "=" )
