Struct MultiOutputManager 

pub struct MultiOutputManager { /* private fields */ }

Multi-output display manager

Implementations

impl MultiOutputManager

pub const fn new() -> Self

Create a new multi-output manager

pub fn init(&mut self)

Initialize the multi-output manager

pub fn add_output( &mut self, connector_id: u32, crtc_id: u32, width: u32, height: u32, refresh_hz: u32, ) -> Result<u32, KernelError>

Add a new display output

The output is placed to the right of all existing outputs by default.

pub fn remove_output(&mut self, output_id: u32) -> Result<(), KernelError>

Remove a display output by ID

pub fn set_position( &mut self, output_id: u32, x: i32, y: i32, ) -> Result<(), KernelError>

Set the position of an output in virtual desktop coordinates

pub fn set_primary(&mut self, output_id: u32) -> Result<(), KernelError>

Set the primary output

pub fn get_outputs(&self) -> &[DisplayOutput]

Get list of active outputs

pub fn get_total_size(&self) -> (u32, u32)

Get total virtual desktop size

pub fn point_to_output(&self, x: i32, y: i32) -> Option<(u32, i32, i32)>

Map a point in virtual desktop coordinates to a specific output

Returns (output_id, local_x, local_y) or None if the point is outside all outputs.

pub fn primary_output(&self) -> Option<&DisplayOutput>

Get the primary output

pub fn get_output(&self, output_id: u32) -> Option<&DisplayOutput>

Get a specific output by ID

pub fn get_output_mut(&mut self, output_id: u32) -> Option<&mut DisplayOutput>

Get a mutable reference to a specific output by ID

pub fn flip(&self, output_id: u32, _buffer_id: u32) -> Result<(), KernelError>

Schedule a page flip on a specific output

In a real implementation this would issue a DRM page flip ioctl.

pub fn handle_hotplug( &mut self, connector_id: u32, connected: bool, width: u32, height: u32, refresh_hz: u32, ) -> Result<(), KernelError>

Handle a DRM connector hotplug event

If connected=true and the connector is new, adds an output. If connected=false, removes the associated output.

pub fn auto_layout(&mut self)

Arrange outputs left-to-right based on their current order

pub fn num_outputs(&self) -> usize

Get the number of active outputs

pub fn is_initialized(&self) -> bool

Check if the manager is initialized

Trait Implementations

impl Default for MultiOutputManager

fn default() -> Self

Returns the “default value” for a type.
