Description

Objects of this type are used to interpret the path as a bidirectional view of segment strings.

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.

Example


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

segments_view ps = u.segments();

assert( ps.buffer().data() == u.buffer().data() );

Percent escapes in strings returned when dereferencing iterators are automatically decoded.

Iterator Invalidation

Changes to the underlying character buffer can invalidate iterators which reference it.
