9    /// A [`TextMark`][crate::TextMark] is a position in a `GtkTextbuffer` that is preserved
10    /// across modifications.
11    ///
12    /// You may wish to begin by reading the
13    /// [text widget conceptual overview](section-text-widget.html),
14    /// which gives an overview of all the objects and data types
15    /// related to the text widget and how they work together.
16    ///
17    /// A [`TextMark`][crate::TextMark] is like a bookmark in a text buffer; it preserves
18    /// a position in the text. You can convert the mark to an iterator using
19    /// [`TextBufferExt::iter_at_mark()`][crate::prelude::TextBufferExt::iter_at_mark()]. Unlike iterators, marks remain
20    /// valid across buffer mutations, because their behavior is defined when
21    /// text is inserted or deleted. When text containing a mark is deleted,
22    /// the mark remains in the position originally occupied by the deleted
23    /// text. When text is inserted at a mark, a mark with “left gravity” will
24    /// be moved to the beginning of the newly-inserted text, and a mark with
25    /// “right gravity” will be moved to the end.
26    ///
27    /// Note that “left” and “right” here refer to logical direction (left
28    /// is the toward the start of the buffer); in some languages such as
29    /// Hebrew the logically-leftmost text is not actually on the left when
30    /// displayed.
31    ///
32    /// Marks are reference counted, but the reference count only controls
33    /// the validity of the memory; marks can be deleted from the buffer at
34    /// any time with [`TextBufferExt::delete_mark()`][crate::prelude::TextBufferExt::delete_mark()]. Once deleted from
35    /// the buffer, a mark is essentially useless.
36    ///
37    /// Marks optionally have names; these can be convenient to avoid passing
38    /// the [`TextMark`][crate::TextMark] object around.
39    ///
