Struct input::Seat

pub struct Seat { /* fields omitted */ }

A seat has two identifiers, the physical name and the logical name.

A device is always assigned to exactly one seat. It may change to a different logical seat but it cannot change physical seats. See Seats for details.

Methods

impl Seat

fn context(&self) -> Libinput

Get the libinput context from the seat.

fn physical_name(&self) -> &str

Return the physical name of the seat.

For libinput contexts created from udev, this is always the same value as passed into udev_assign_seat and all seats from that context will have the same physical name.

The physical name of the seat is one that is usually set by the system or lower levels of the stack. In most cases, this is the base filter for devices - devices assigned to seats outside the current seat will not be available to the caller.

fn logical_name(&self) -> &str

Return the logical name of the seat.

This is an identifier to group sets of devices within the compositor.
