#[repr(transparent)]pub struct TextMark { /* private fields */ }Expand description
You may wish to begin by reading the [text widget conceptual overview][TextWidget] which gives an overview of all the objects and data types related to the text widget and how they work together.
A TextMark is like a bookmark in a text buffer; it preserves a position in
the text. You can convert the mark to an iterator using
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(). Once deleted from the buffer, a mark is
essentially useless.
Marks optionally have names; these can be convenient to avoid passing the
TextMark object around.
Marks are typically created using the TextBufferExt::create_mark() function.

Implementations
sourceimpl TextMark
impl TextMark
pub const NONE: Option<&'static TextMark> = None
sourcepub fn new(name: Option<&str>, left_gravity: bool) -> TextMark
pub fn new(name: Option<&str>, left_gravity: bool) -> TextMark
Creates a text mark. Add it to a buffer using TextBufferExt::add_mark().
If name is None, the mark is anonymous; otherwise, the mark can be
retrieved by name using TextBufferExt::mark(). If a mark has left
gravity, and text is inserted at the mark’s current location, the mark
will be moved to the left of the newly-inserted text. If the mark has
right gravity (left_gravity = false), the mark will end up on the
right of newly-inserted text. The standard left-to-right cursor is a
mark with right gravity (when you type, the cursor stays on the right
side of the text you’re typing).
name
mark name or None
left_gravity
whether the mark should have left gravity
Returns
new TextMark
sourcepub fn builder() -> TextMarkBuilder
pub fn builder() -> TextMarkBuilder
Creates a new builder-pattern struct instance to construct TextMark objects.
This method returns an instance of TextMarkBuilder which can be used to create TextMark objects.
