Data Members

Name	Description
has_value	True if the value is present.
key	The percent-decoded key.
value	The percent-decoded value.

Objects of this type represent a single key/value pair 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. Ownership of the underlying character buffers representing the key and value is not transferred. The caller is responsible for ensuring that the buffers assigned to these members remains valid while the object exists.

Description

This type does not make a copy of a parameter and ownership is retained by the container.
