Description

max_size

Return the maximum number of characters possible.

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() );

The strings produced when iterators are dereferenced belong to the iterator and become invalidated when that particular iterator is incremented, decremented, or destroyed. Any percent-escapes in returned strings are decoded first.

Iterator Invalidation

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