pub fn itemize( context: &Context, text: &str, start_index: i32, length: i32, attrs: &AttrList, cached_iter: Option<&AttrIterator<'_>> ) -> Vec<Item>
Breaks a piece of text into segments with consistent directional level and font.
Each byte of @text will be contained in exactly one of the items in the returned list; the generated list of items will be in logical order (the start offsets of the items are ascending).
@cached_iter should be an iterator over @attrs currently positioned at a range before or containing @start_index; @cached_iter will be advanced to the range covering the position just after @start_index + @length. (i.e. if itemizing in a loop, just keep passing in the same @cached_iter).
a structure holding information that affects the itemization process.
the text to itemize. Must be valid UTF-8
first byte in @text to process
the number of bytes (not characters) to process after @start_index. This must be >= 0.
the set of attributes that apply to @text.

Item structures. The items should be freed using
Pango::Item::free() in combination with
