Synopsis

Declared in <boost/url/pct_string_view.hpp>

template<string_token::StringToken StringToken = string_token::return_string>

    StringToken&& token) const;

Example

assert( pct_string_view( "Program%20Files" ).decode() == "Program Files" );

Calls to allocate may throw. String tokens may throw exceptions.

The decoded string.
