overflow: OverflowInfo

Information about content that did not fit.

Implementations

impl UnifiedLayout

pub fn bounds(&self) -> Rect

Calculate the bounding box of all positioned items. This is computed on-demand rather than cached.

pub const fn is_empty(&self) -> bool

pub fn first_baseline(&self) -> Option<f32>

pub fn last_baseline(&self) -> Option<f32>

pub fn hittest_cursor(&self, point: LogicalPosition) -> Option<TextCursor>

Takes a point relative to the layout’s origin and returns the closest logical cursor position.

This is the unified hit-testing implementation. The old hit_test_to_cursor method is deprecated in favor of this one.

pub fn get_selection_rects(&self, range: &SelectionRange) -> Vec<LogicalRect>

Given a logical selection range, returns a vector of visual rectangles that cover the selected text, in the layout’s coordinate space.

pub fn get_cursor_rect(&self, cursor: &TextCursor) -> Option<LogicalRect>

Calculates the visual rectangle for a cursor at a given logical position.

pub fn get_first_cluster_cursor(&self) -> Option<TextCursor>

Get a cursor at the first cluster (leading edge) in the layout.

pub fn get_last_cluster_cursor(&self) -> Option<TextCursor>

Get a cursor at the last cluster (trailing edge) in the layout.

pub fn move_cursor_left( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor one visible position to the left (the previous grapheme boundary). Affinity is consulted so each press moves exactly one stop and the document start (first grapheme, Leading) is reachable; combining marks move together with their base.

pub fn move_cursor_right( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor one visible position to the right (the next grapheme boundary). Affinity is consulted so each press moves exactly one stop and the document end (last grapheme, Trailing) is reachable; combining marks move together with their base.

pub fn move_cursor_up( &self, cursor: TextCursor, goal_x: &mut Option<f32>, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor up one line, attempting to preserve the horizontal column.

pub fn move_cursor_down( &self, cursor: TextCursor, goal_x: &mut Option<f32>, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor down one line, attempting to preserve the horizontal column.

pub fn move_cursor_to_line_start( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor to the visual start of its current line.

pub fn move_cursor_to_line_end( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor to the visual end of its current line.

pub fn move_cursor_to_prev_word( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor one word to the left (Ctrl+Left / Option+Left).

Word boundaries use the shared [is_word_char] predicate (alphanumeric or underscore are word characters; whitespace AND punctuation are boundaries), so this agrees with double-click word selection. The cursor moves past any boundary clusters to the left, then past word clusters until the next boundary or start of text.

pub fn move_cursor_to_next_word( &self, cursor: TextCursor, debug: &mut Option<Vec<String>>, ) -> TextCursor

Moves a cursor one word to the right (Ctrl+Right / Option+Right).

Word boundaries use the shared [is_word_char] predicate (alphanumeric or underscore are word characters; whitespace AND punctuation are boundaries), so this agrees with double-click word selection. The cursor moves past any word clusters, then past boundary clusters until the next word or end of text.
