Struct PointerSeat 

#[repr(C)]
pub struct PointerSeat {
    pub seat_id: u64,
    pub state: MouseState,
}

One ADDITIONAL pointer seat (9b-ii): an independent cursor with its own position, buttons and hover, next to the primary one.

A SEAT is not a DEVICE. MouseState::pointer_device_id names the physical hardware that last drove a cursor; a seat is the cursor itself. The distinction is the whole design: on Windows, macOS, Android and iOS the OS merges every mouse into ONE cursor, so two mice are two devices driving one seat - a click from the second mouse after a move from the first lands where the first left the cursor, because that IS where the cursor is. Keying state by device would have split that one cursor into two entries with different positions, and dispatched the click somewhere the user could not see. Only X11 (MPX master pointers) and Wayland (one wl_seat per user) can present a second cursor, and only there does a second entry exist.

The primary seat is NOT in pointer_seats; it stays mouse_state so every existing reader of “the mouse” keeps meaning what it meant.

Fields

seat_id: u64

The platform’s identity for this cursor - an X11 master pointer id, a Wayland seat’s global name. Never PRIMARY_POINTER_SEAT.

state: MouseState

The seat’s own cursor state.
