Implementations

impl TextSelection

pub fn new_cursor(pos: usize) -> Self

Create a new TextSelection::Cursor

pub fn new_range((from, to): (usize, usize)) -> Self

Create a new TextSelection::Range

pub fn pos(&self) -> usize

Get the position

pub fn set_as_cursor(&mut self)

Set the selection as a cursor

pub fn set_as_range(&mut self)

Set the selection as a range

pub fn start(&self) -> usize

Get the start of the cursor position.

pub fn end(&self) -> usize

Get the end of the cursor position.

pub fn move_to(&mut self, position: usize)

Move the end position of the cursor.

pub fn is_range(&self) -> bool

Trait Implementations

impl Clone for TextSelection

fn clone(&self) -> TextSelection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextSelection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TextSelection

fn eq(&self, other: &TextSelection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
