Struct TextInputLayout 

pub struct TextInputLayout {
    pub bounds: Rect,
    pub content_bounds: Rect,
    pub visible_lines: Vec<VisibleTextInputLine>,
    pub cursor_bounds: Option<Rect>,
    pub resolved_scroll_offset: usize,
    pub resolved_scroll_col: usize,
    pub hit_regions: Vec<(Rect, TextInputHit)>,
    pub placeholder_active: bool,
}

Fully-resolved layout.

Fields

bounds: Rect

Outer bounds (matches the rect argument to layout).

content_bounds: Rect

Content bounds (inside any border/padding the rasteriser draws).

visible_lines: Vec<VisibleTextInputLine>

cursor_bounds: Option<Rect>

Cursor bounds in viewport pixels/cells when the cursor is inside the visible window, otherwise None. Rasterisers paint a cursor glyph (TUI) or vertical bar (GTK) at this rect.

resolved_scroll_offset: usize

Vertical scroll offset after auto-clamp. The primitive guarantees the cursor is visible by adjusting this.

resolved_scroll_col: usize

Horizontal scroll offset (char columns) after auto-clamp. Rasterisers slice each line [resolved_scroll_col..] before painting.

hit_regions: Vec<(Rect, TextInputHit)>

Per-region hit map for click routing.

placeholder_active: bool

True when the placeholder was rendered (lines empty / single empty line). Rasterisers consult this to draw the placeholder in a muted color.

Implementations

impl TextInputLayout

pub fn hit_test(&self, x: f32, y: f32) -> TextInputHit

Hit-test a click at surface-native coordinates (x, y) against this layout’s hit_regions.

Coordinate frame: ABSOLUTE — matches TextInputLayout’s own convention (bounds/content_bounds/hit_regions all carry rect.x/rect.y, per PRIMITIVE_RULES.md’s coordinate-frame table). Returns TextInputHit::EmptyArea when (x, y) falls outside every region.
