Struct Selection 

pub struct Selection { /* private fields */ }

A list of SelectionRanges — NEVER empty (enforced by keeping the backing Vec private behind constructors that always seed one range). TextInput/TextArea only ever populate the primary (last) range; the list shape exists so a future multi-cursor widget is additive, not a rewrite (D116).

Implementations

impl Selection

pub fn single(pos: usize) -> Self

pub fn range(anchor: usize, head: usize) -> Self

pub fn primary(&self) -> &SelectionRange

The primary (most-recently-active) range — for single-cursor widgets, the only one that exists.

pub fn primary_range(&self) -> (usize, usize)

pub fn ranges(&self) -> &[SelectionRange]
