Function pango::itemize

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 shaping engine. 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).

context

a structure holding information that affects the itemization process.

text

the text to itemize. Must be valid UTF-8

start_index

first byte in text to process

length

the number of bytes (not characters) to process after start_index. This must be >= 0.

attrs

the set of attributes that apply to text.

cached_iter

Cached attribute iterator, or None

Returns

a GList of Item structures. The items should be freed using pango_item_free() probably in combination with g_list_foreach(), and the list itself using g_list_free().
