Struct Caret 

pub struct Caret {
    pub line: usize,
    pub column: usize,
    pub selected: usize,
}

Where the caret sits — its line and column, both counted from 1, the column in characters — and how many characters the selection spans.

Fields

line: usize

column: usize

selected: usize

Implementations

impl Caret

pub fn of(text: &str, start: usize, end: usize, backward: bool) -> Caret

The caret in text for a selection from start to end, offsets in UTF-16 code units as the browser counts them. The caret is the selection’s moving end: start when the selection was made backwards, end otherwise.

pub fn label(&self) -> String

“Ln 3, Col 4”, with “(2 selected)” after it while text is selected.

Trait Implementations

impl Clone for Caret

fn clone(&self) -> Caret

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Caret

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

Formats the value using the given formatter.

impl Default for Caret

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Caret

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