== Description


This function returns a bidirectional        view of segments over the path&period;        The returned view references the same        underlying character buffer&semi; ownership        is not transferred&period;        Any percent&hyphen;escapes in strings returned        when iterating the view are decoded first&period;        The container is modifiable&semi; changes        to the container are reflected in the        underlying URL&period;


=== Example

[,cpp]
----
url u( "http://example.com/path/to/file.txt" );

segments sv = u.segments();
----

=== Complexity

Constant&period;


=== Exception Safety

Throws nothing&period;


=== 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>
