explicit
static_url(core::string_view s);

== Description

This function constructs a url from the string `s`, which must contain a valid _URI_ or _relative‐ref_ or else an exception is thrown. The new url retains ownership by making a copy of the passed string.

== Example
[,cpp]
----
static_url< 1024 > u( "https://www.example.com" );
----
== Effects

----
return static_url( parse_uri_reference( s ).value() );
----
== Postconditions
[,cpp]
----
this->buffer().data() != s.data()
----
== Complexity
Linear in `s&period;size()`&period;

== Exception Safety
Exceptions thrown on invalid input&period;

== BNF
[,cpp]
----
URI           = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

relative-ref  = relative-part [ "?" query ] [ "#" fragment ]
