segments_encoded_ref A view representing path segments in a URL
url_base Common functionality for containers

Description

Objects of this type are used to interpret the path as a bidirectional view of segments, where each segment is a string with percent escapes automatically decoded.

The view does not retain ownership of the elements and instead references the original character buffer. The caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced.

The view is modifiable; calling non-const members causes changes to the referenced url.

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:
