Struct Selection 

pub struct Selection {
    pub anchor: Position,
    pub head: Position,
}

A selection in the document. anchor is where the selection started, head is where the cursor currently is. When anchor == head, it’s a simple cursor with no selected text.

Fields

anchor: Position

head: Position

Implementations

impl Selection

pub fn cursor(pos: Position) -> Self

A cursor at the given position (no selected text).

pub fn new(anchor: Position, head: Position) -> Self

A selection from anchor to head.

pub fn start(&self) -> Position

The earlier of anchor/head.

pub fn end(&self) -> Position

The later of anchor/head.

pub fn is_cursor(&self) -> bool

True if no text is selected (cursor only).

pub fn is_backward(&self) -> bool

True if the selection extends backward (head before anchor).

Trait Implementations

impl Clone for Selection

fn clone(&self) -> Selection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selection

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

Formats the value using the given formatter.

impl PartialEq for Selection

fn eq(&self, other: &Selection) -> 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.

impl Copy for Selection

impl Eq for Selection
