Struct IdleInhibitManager 

pub struct IdleInhibitManager { /* private fields */ }

Manages idle inhibitors and queries the global idle-inhibited state.

Implementations

impl IdleInhibitManager

pub fn new() -> Self

Create a new idle inhibit manager.

pub fn create_inhibitor(&mut self, surface_id: u32) -> Result<u32, KernelError>

Create a new inhibitor for the specified surface.

Returns the inhibitor ID assigned by the manager.

pub fn destroy_inhibitor(&mut self, id: u32) -> Result<(), KernelError>

Destroy an inhibitor by its object ID.

pub fn remove_inhibitors_for_surface(&mut self, surface_id: u32) -> usize

Remove all inhibitors associated with a specific surface.

Called when a surface is destroyed to clean up its inhibitors. Returns the number of inhibitors removed.

pub fn is_idle_inhibited(&self) -> bool

Check whether idle should be inhibited.

Returns true if at least one active inhibitor exists. In a full implementation, this would also check whether the inhibitor’s surface is currently visible/mapped.

pub fn active_count(&self) -> usize

Get the number of active inhibitors.

pub fn get_inhibitor(&self, id: u32) -> Option<&IdleInhibitor>

Get a reference to a specific inhibitor.

pub fn inhibitor_count(&self) -> usize

Total number of inhibitors (active and inactive).

Trait Implementations

impl Default for IdleInhibitManager

fn default() -> Self

Returns the “default value” for a type.
