Struct MouseEventData 

#[repr(C)]
pub struct MouseEventData {
    pub position: LogicalPosition,
    pub button: MouseButton,
    pub buttons: u8,
    pub modifiers: KeyModifiers,
    pub source: PointerSource,
    pub device_id: u64,
    pub seat_id: u64,
}

Type-specific event data for mouse events.

Fields

position: LogicalPosition

Position of the mouse cursor

button: MouseButton

Which button was pressed/released

buttons: u8

Bitmask of currently pressed buttons

modifiers: KeyModifiers

Modifier keys state

source: PointerSource

What produced this event. APPENDED for ABI stability.

device_id: u64

Which physical device produced it, or 0 when the platform does not say. APPENDED for ABI stability.

Only PenState, GamepadState and TabletPadState carried a device id before, so a mouse event could not say WHICH of two mice moved — and MouseState used to be a single global, which is why multi-seat (a kiosk, a shared display, two people on one compositor) was not expressible at all. The state fans out per seat since 9b-ii; this field stays the PHYSICAL device, seat_id below says which cursor.

seat_id: u64

Which pointer SEAT - which independent cursor - produced it. APPENDED (9b-ii). PRIMARY_POINTER_SEAT (0) for the ordinary mouse, which is every event on a platform with one cursor; an X11 MPX master id or a Wayland seat otherwise. A callback that receives a non-zero value reads that seat’s state through get_pointer_seat_state, because get_current_mouse_state is the PRIMARY seat by definition.
