Struct pango::AttrIterator

source ·
pub struct AttrIterator<'list> { /* private fields */ }
Expand description

A AttrIterator is used to iterate through a AttrList.

A new iterator is created with AttrList::iterator(). Once the iterator is created, it can be advanced through the style changes in the text using next_style_change(). At each style change, the range of the current style segment and the attributes currently in effect can be queried.
