Struct UnifiedDragContext 

pub struct UnifiedDragContext {
    pub drag_type: ActiveDragType,
    pub session_id: u64,
    pub cancelled: bool,
}

The unified drag context.

This struct wraps ActiveDragType and provides common metadata that applies to all drag operations.

Fields

drag_type: ActiveDragType

The specific type of drag operation

session_id: u64

Session ID from gesture detection (links back to GestureManager)

cancelled: bool

Whether the drag has been cancelled (e.g., Escape pressed)

Trait Implementations

impl Clone for DragContext

fn clone(&self) -> DragContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DragContext

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

Formats the value using the given formatter.

impl PartialEq for DragContext

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