boost::urls::grammar::ref

Return a reference to a character set

Synopsis

Declared in <boost/url/grammar/charset.hpp>

template<CharSet CS>
constexpr
/* implementation-defined */
ref(CS const& cs) noexcept
requires is_charset<CS>::value &&
    ! std::is_same<CS,
        implementation_defined::charset_ref<CS> >::value;

Description

This function returns a character set which references the specified object. This is used to reduce the number of bytes of storage (sizeof) required by a combinator when it stores a copy of the object. Ownership of the object is not transferred; the caller is responsible for ensuring the lifetime of the object is extended until it is no longer referenced. For best results, ref should only be used with compile‐time constants.

Return Value

The character set as a reference type
