You can convert the mark to an iterator using /// [`TextBufferExt::iter_at_mark()`][crate::prelude::TextBufferExt::iter_at_mark()]. Unlike iterators, marks remain valid across /// buffer mutations, because their behavior is defined when text is inserted or /// deleted. When text containing a mark is deleted, the mark remains in the /// position originally occupied by the deleted text. When text is inserted at a /// mark, a mark with “left gravity” will be moved to the /// beginning of the newly-inserted text, and a mark with “right /// gravity” will be moved to the end. /// /// Note that “left” and “right” here refer to logical direction (left /// is the toward the start of the buffer); in some languages such as /// Hebrew the logically-leftmost text is not actually on the left when /// displayed. /// /// Marks are reference counted, but the reference count only controls the validity /// of the memory; marks can be deleted from the buffer at any time with /// [`TextBufferExt::delete_mark()`][crate::prelude::TextBufferExt::delete_mark()].
