Struct TextSelection 

pub struct TextSelection { /* private fields */ }

Anchor/head text selection used by frontend integrations.

Qem keeps this selection in document coordinates so applications remain free to own their own painting, cursor visuals, and interaction model.

Implementations

impl TextSelection

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

Creates a selection from an anchor and active head position.

pub const fn caret(position: TextPosition) -> Self

Creates a caret selection at a single position.

pub const fn anchor(self) -> TextPosition

Returns the anchor position.

pub const fn head(self) -> TextPosition

Returns the active head position.

pub fn is_caret(self) -> bool

Returns true when the selection is only a caret.

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 Default for TextSelection

fn default() -> TextSelection

Returns the “default value” for a type.

impl Hash for TextSelection

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
