== Description


After construction, both views        reference the same url. Ownership is not        transferred; the caller is responsible        for ensuring the lifetime of the url        extends until it is no longer        referenced.


=== Postconditions

[,cpp]
----
&this->url() == &other.url()
----

=== Complexity

Constant.


=== Exception Safety

Throws nothing.



== Parameters


|===
| Name | Description

| *other*
| The other view.


| *opt*
| The options for decoding. If        this parameter is omitted, `space_as_plus`        is used.
