Conversion |
Description
Presents the decoded path segments of a url_base as a bidirectional range whose modifiers update the underlying URL. The proxy references the URL’s storage directly, so the owning URL must remain alive while the proxy is used.
Example
url u( "/path/to/file.txt" );
segments_ref ps = u.segments();Percent escapes in strings returned when dereferencing iterators are automatically decoded. Reserved characters in strings supplied to modifier functions are automatically percent‐escaped.
Iterator Invalidation
Changes to the underlying character buffer can invalidate iterators which reference it. Modifications made through the container invalidate some or all iterators:
-
push_back: Only `end()`. -
assign,clear,operator=: All elements. -
erase: Erased elements and all elements after (including `end()`). -
insert: All elements at or after the insertion point (including `end()`). -
replace: Modified elements and all elements after (including `end()`).
