pub struct Seat { /* private fields */ }Implementations§
Methods from Deref<Target = SeatRef>§
Sourcepub fn disable(&mut self) -> Result<(), Errno>
pub fn disable(&mut self) -> Result<(), Errno>
Disables a seat, used in response to a disable_seat event. After disabling the seat, the seat devices must not be used until enable_seat is received, and all requests on the seat will fail during this period.
Sourcepub fn open_device<P: AsRef<Path>>(&mut self, path: &P) -> Result<Device, Errno>
pub fn open_device<P: AsRef<Path>>(&mut self, path: &P) -> Result<Device, Errno>
Opens a device on the seat, returning its device ID and fd
This will only succeed if the seat is active and the device is of a type permitted for opening on the backend, such as drm and evdev.
The device may be revoked in some situations, such as in situations where a seat session switch is being forced.
Sourcepub fn close_device(&mut self, device: Device) -> Result<(), Errno>
pub fn close_device(&mut self, device: Device) -> Result<(), Errno>
Closes a device that has been opened on the seat using the device_id from libseat_open_device.
Sourcepub fn name(&mut self) -> &str
pub fn name(&mut self) -> &str
Retrieves the name of the seat that is currently made available through the provided libseat instance.
Sourcepub fn switch_session(&mut self, session: i32) -> Result<(), Errno>
pub fn switch_session(&mut self, session: i32) -> Result<(), Errno>
Requests that the seat switches session to the specified session number. For seats that are VT-bound, the session number matches the VT number, and switching session results in a VT switch.
A call to libseat_switch_session does not imply that a switch will occur, and the caller should assume that the session continues unaffected.
Sourcepub fn get_fd(&mut self) -> Result<BorrowedFd<'_>, Errno>
pub fn get_fd(&mut self) -> Result<BorrowedFd<'_>, Errno>
Retrieve the pollable connection fd for a given libseat instance. Used to poll the libseat connection for events that need to be dispatched.
Returns a pollable fd on success.
Sourcepub fn dispatch(&mut self, timeout: i32) -> Result<i32, Errno>
pub fn dispatch(&mut self, timeout: i32) -> Result<i32, Errno>
Reads and dispatches events on the libseat connection fd.
The specified timeout dictates how long libseat might wait for data if none is available: 0 means that no wait will occur, -1 means that libseat might wait indefinitely for data to arrive, while > 0 is the maximum wait in milliseconds that might occur.
Returns a positive number signifying processed internal messages on success. Returns 0 if no messages were processed. Returns -1 and sets errno on error.
