= Function segments_encoded_ref::assign

pass:v,q[Assign segments]


== Synopsis

Declared in header `</boost/url/segments_encoded_ref.hpp#L321[boost/url/segments_encoded_ref.hpp,window=blank_]>`

[source,cpp,subs="verbatim,macros,-callouts"]
----
void
assign(initializer_list<xref:boost/urls/pct_string_view.adoc[pct_string_view]> init);
----

== Description

pass:v,q[The existing contents are replaced] pass:v,q[by a copy of the contents of the]
pass:v,q[initializer list.]
pass:v,q[Reserved characters in the list are]
pass:v,q[automatically escaped.]
pass:v,q[Escapes in the list are preserved.]
pass:v,q[All iterators are invalidated.]
[NOTE]
pass:v,q[None of the character buffers referenced]
pass:v,q[by the list may overlap the character]
pass:v,q[buffer of the underlying url, or else]
pass:v,q[the behavior is undefined.]

=== Example
[,cpp]
----
url u;

u.segments().assign( {"path", "to", "file.txt"} );
----

=== Complexity
pass:v,q[Linear in `init.size() + this->url().encoded_query().size() + this->url().encoded_fragment().size()`.]

=== Exception Safety
pass:v,q[Strong guarantee.]
pass:v,q[Calls to allocate may throw.]
pass:v,q[Exceptions thrown on invalid input.]
