== Synopsis


Declared in `&lt;https://www.github.com/boostorg/url/blob/develop/include/boost/url/segments_encoded_ref.hpp#L211[boost&sol;url&sol;segments&lowbar;encoded&lowbar;ref&period;hpp]&gt;`

xref:boost/urls/segments_encoded_ref.adoc[segments&lowbar;encoded&lowbar;ref]&
operator&equals;(std::initializer&lowbar;list&lt;xref:boost/urls/pct_string_view.adoc[pct&lowbar;string&lowbar;view]&gt; init);
----

== Description


The existing contents are replaced        by a copy of the contents of the        initializer list&period;        Reserved characters in the list are        automatically escaped&period;        Escapes in the list are preserved&period;

All iterators are invalidated&period;


=== Example

[,cpp]
----
url u;

u.encoded_segments() = {"path", "to", "file.txt"};
----

=== Preconditions

None of the character buffers referenced        by the list may overlap the character buffer        of the underlying url, or else the behavior        is undefined&period;


=== Effects

[,cpp]
----
this->assign( init.begin(), init.end() );
----

=== Complexity

Linear in `init&period;size() &plus; this&hyphen;&gt;url()&period;encoded&lowbar;query()&period;size() &plus; this&hyphen;&gt;url()&period;encoded&lowbar;fragment()&period;size()`&period;


=== Exception Safety

Strong guarantee&period;        Calls to allocate may throw&period;        Exceptions thrown on invalid input&period;



== Exceptions


|===
| Name | Thrown on

| `system&lowbar;error`
| The list contains an invalid percent&hyphen;encoding&period;

== Parameters


|===
| Name | Description

| *init*
| The list of segments to assign&period;
