Struct Selection 

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

Selection defined by anchor (fixed) and head (moving with cursor).

Fields

anchor: CursorPosition

The fixed end of the selection.

head: CursorPosition

The moving end (same as cursor).

Implementations

impl Selection

pub fn byte_range(&self, nav: &CursorNavigator<'_>) -> (usize, usize)

Byte range of the selection (start, end) where start <= end.

pub fn is_empty(&self) -> bool

Whether the selection is empty (anchor == head).

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
