pub fn init( self: &SuspendResumeManagerHandle, system_task: &CurrentTask, ) -> Result<(), Error>

Power on the PowerMode element and start listening to the suspend stats updates.

pub fn add_lock(&self, name: &str, src: LockSource) -> bool

Adds a wake lock name to the active wake locks.

pub fn remove_lock(&self, name: &str) -> bool

Removes a wake lock name from the active wake locks.

pub fn add_epoll(&self, current_task: &CurrentTask, key: EpollKey)

Adds a wake lock key to the active epoll wake locks.

pub fn remove_epoll(&self, key: EpollKey)

Removes a wake lock key from the active epoll wake locks.

pub fn add_message_counter( &self, name: &str, counter: Option<Counter>, ) -> OwnedMessageCounterHandle

pub fn has_nonzero_message_counter(&self) -> bool

pub fn duplicate_lock_event(&self) -> EventPair

Returns a duplicate handle to the EventPair that is signaled when wake locks are active.

pub fn suspend_stats(&self) -> SuspendStats

Gets the suspend statistics.

pub fn sync_on_suspend_enabled(&self) -> bool

Get the contents of the power “sync_on_suspend” file in the power filesystem. True will cause 1 to be reported, and false will cause 0 to be reported.

pub fn set_sync_on_suspend(&self, enable: bool)

Get the contents of the power “sync_on_suspend” file in the power filesystem. See also [sync_on_suspend_enabled].

pub fn suspend_states(&self) -> HashSet<SuspendState>

Returns the supported suspend states.

pub fn suspend( &self, locked: &mut Locked<FileOpsCore>, state: SuspendState, ) -> Result<(), Errno>

pub fn acquire_ebpf_suspend_lock<'a, L>( &'a self, locked: &'a mut Locked<L>, ) -> EbpfSuspendGuard<'a>

where L: LockBefore<EbpfSuspendLock>,
