Assignment

== Synopsis


Declared in `<https://www.github.com/boostorg/url/blob/develop/include/boost/url/segments_ref.hpp#L203[boost/url/segments_ref.hpp]>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
xref:boost/urls/segments_ref.adoc[segments_ref]&
operator=(std::initializer_list<core::string_view> init);
----

== Description


The existing contents are replaced        by a copy of the contents of the        initializer list.        Reserved characters in the list are        automatically escaped.

All iterators are invalidated.


=== Example

[,cpp]
----
url u;

u.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.


=== Effects

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

=== Complexity

Linear in `init.size() + this‐>url().encoded_query().size() + this‐>url().encoded_fragment().size()`.


=== Exception Safety

Strong guarantee.        Calls to allocate may throw.



== Parameters


|===
| Name | Description

| *init*
| The list of segments to assign.
