Struct SelectionAnchor 

pub struct SelectionAnchor {
    pub ifc_root_node_id: NodeId,
    pub cursor: TextCursor,
    pub char_bounds: LogicalRect,
    pub mouse_position: LogicalPosition,
}

The anchor point of a text selection - where the user started selecting.

This is the fixed point during a drag operation. It records:

• The IFC root node (where the UnifiedLayout lives)
• The exact cursor position within that layout
• The visual bounds of the anchor character (for logical rectangle calculations)

The anchor remains constant during a drag; only the focus moves.

Fields

ifc_root_node_id: NodeId

The IFC root node ID where selection started. This is the node that has inline_layout_result (e.g., <p>, <div>).

cursor: TextCursor

The exact cursor position within the IFC’s UnifiedLayout.

char_bounds: LogicalRect

Visual bounds of the anchor character in viewport coordinates. Used for computing the logical selection rectangle during multi-line/multi-node selection.

mouse_position: LogicalPosition

The mouse position when the selection started (viewport coordinates).

Trait Implementations

impl Clone for SelectionAnchor

fn clone(&self) -> SelectionAnchor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionAnchor

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

Formats the value using the given formatter.

impl PartialEq for SelectionAnchor

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