Set the path.

== Synopsis


Declared in `<https://www.github.com/boostorg/url/blob/develop/include/boost/url/static_url.hpp#L401[boost/url/static_url.hpp]>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]

xref:boost/urls/static_url.adoc[static_url]&
set_path(core::string_view s);
----

== Description


This function sets the path to the        string, which may be empty.        Reserved characters in the string are        percent‐escaped in the result.

[NOTE]
The library may adjust the final result        to ensure that no other parts of the url        is semantically affected.

[NOTE]
This function does not encode '/' chars, which        are unreserved for paths but reserved for        path segments. If a path segment should include        encoded '/'s to differentiate it from path separators,        the functions xref:boost/urls/url_base/set_encoded_path.adoc[set_encoded_path] or xref:boost/urls/url_base/segments-04.adoc[segments]        should be used instead.


=== Example

[,cpp]
----
url u( "http://www.example.com" );

u.set_path( "path/to/file.txt" );

assert( u.path() == "/path/to/file.txt" );
----

=== Complexity

Linear in `this‐>size() + s.size()`.


=== Exception Safety

Strong guarantee.        Calls to allocate may throw.


=== BNF

[,cpp]
----
path          = path-abempty    ; begins with "/" or is empty
              / path-absolute   ; begins with "/" but not "//"
              / path-noscheme   ; begins with a non-colon segment
              / path-rootless   ; begins with a segment
              / path-empty      ; zero characters

path-abempty  = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
path-rootless = segment-nz *( "/" segment )
path-empty    = 0<pchar>
