pub trait Suspendable {
// Provided methods

}Expand description
This trait provides the functions required for a device to implement to successfully suspend/resume in crosvm.
Provided Methods§
Sourcefn snapshot(&mut self) -> Result<AnySnapshot>
fn snapshot(&mut self) -> Result<AnySnapshot>
Save the device state in an image that can be restored.
Sourcefn restore(&mut self, _data: AnySnapshot) -> Result<()>
fn restore(&mut self, _data: AnySnapshot) -> Result<()>
Load a saved snapshot of an image.

impl Suspendable for Ioapic
impl Suspendable for Pic
The PIC is only used in very early boot on x86_64, and snapshots are not generally taken during that time, so we can safely skip the PIC for now.
