Struct Selection 

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

Selection represents a range with a direction

The anchor is where the selection started, and the cursor is where it currently ends. This allows tracking selection direction.

Fields

anchor: Position

Where the selection started

cursor: Position

Where the selection cursor is

Implementations

impl Selection

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

Create a new selection

pub const fn empty(pos: Position) -> Self

Create an empty selection at position

pub const fn is_empty(&self) -> bool

Check if selection is empty (no selected text)

pub fn range(&self) -> Range

Get the range covered by this selection (normalized)

pub const fn is_reversed(&self) -> bool

Check if selection is reversed (cursor before anchor)

pub const fn extend_to(&self, pos: Position) -> Self

Extend selection to include a position

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

impl StructuralPartialEq for Selection
