Expand description

This trait provides the functions required for a device to implement to successfully suspend/resume in crosvm.

Provided Methods§

source

fn snapshot(&mut self) -> Result<Value>

Save the device state in an image that can be restored.

source

fn restore(&mut self, _data: Value) -> Result<()>

Load a saved snapshot of an image.

source

fn sleep(&mut self) -> Result<()>

Stop all threads related to the device. Sleep should be idempotent.

source

fn wake(&mut self) -> Result<()>

Create/Resume all threads related to the device. Wake should be idempotent.
