Struct kernel::power::NoOperations

source · [−]

pub struct NoOperations<T: ForeignOwnable>(_);

Expand description

Implements the Operations trait as no-ops.

This is useful when one doesn’t want to provide the implementation of any power-manager related operation.

Trait Implementations

source

impl<T: ForeignOwnable + Send + Sync> Operations for NoOperations<T>

type Data = T

The type of the context data stored by the driver on each device.

source

fn suspend(_data: <Self::Data as ForeignOwnable>::Borrowed<'_>) -> Result

Called before the system goes into a sleep state.

source

fn resume(_data: <Self::Data as ForeignOwnable>::Borrowed<'_>) -> Result

Called after the system comes back from a sleep state.

source

fn freeze(_data: <Self::Data as ForeignOwnable>::Borrowed<'_>) -> Result

Called before creating a hibernation image.

source

fn restore(_data: <Self::Data as ForeignOwnable>::Borrowed<'_>) -> Result

Called after the system is restored from a hibernation image.
