Enum TextMovement

pub enum TextMovement {
    Left,
    Right,
    WordLeft,
    WordRight,
    LineStart,
    LineEnd,
    DocumentStart,
    DocumentEnd,
    LineUp,
    LineDown,
    PageUp,
    PageDown,
}

Caret movement direction for keyboard navigation.

Horizontal character movement follows Unicode extended grapheme clusters. Words are whitespace-delimited; punctuation remains part of a word. Vertical movement uses newline-delimited logical lines and preserves a grapheme column, not shaped X geometry. Page movement is exactly ten logical lines.

Examples

use ailloli_ui_text::TextMovement;
assert_ne!(TextMovement::Left, TextMovement::WordLeft);
assert_ne!(TextMovement::LineUp, TextMovement::PageUp);

Variants

Left

Move to the previous extended grapheme boundary.

Right

Move to the next extended grapheme boundary.

WordLeft

Move left across whitespace and then to the current word’s start.

WordRight

Move right across whitespace and through the next non-whitespace run.

LineStart

Move after the previous newline, or byte zero on the first line.

LineEnd

Move before the next newline, or to document end on the last line.

DocumentStart

Move to UTF-8 byte zero.

DocumentEnd

Move to the document’s UTF-8 byte length.

LineUp

Move one logical line up at the same grapheme column when possible.

LineDown

Move one logical line down at the same grapheme column when possible.

PageUp

Move ten logical lines up at the same grapheme column when possible.

PageDown

Move ten logical lines down at the same grapheme column when possible.

Trait Implementations

impl Clone for TextMovement

fn clone(&self) -> TextMovement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextMovement

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

Formats the value using the given formatter.

impl PartialEq for TextMovement

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