has_value	True if the value is present.
key	The key.
value	The value.

Objects of this type represent a single key/value pair, possibly percent-encoded, in a query string. A value that is present with an empty string is distinct from a value that is absent. The presence of a value is indicated by has_value == true. Whether the strings are percent-encoded is determined by the container from which the value is obtained. This type allows for making a copy of a parameter where ownership is retained in the copy.
