Trait MigratableKernel 

pub trait MigratableKernel: CheckpointableKernel {
    // Required methods
    fn prepare_for_migration(&mut self) -> Result<(), RingKernelError>;
    fn cancel_migration(&mut self) -> Result<(), RingKernelError>;

    fn estimated_state_size(&self) -> usize;
}

Trait for kernels that support live migration.

Required Methods

fn prepare_for_migration(&mut self) -> Result<(), RingKernelError>

Prepare kernel for migration (quiesce, drain messages).

fn cancel_migration(&mut self) -> Result<(), RingKernelError>

Resume kernel after migration is cancelled.

fn is_quiescent(&self) -> bool

Check if kernel is ready to be checkpointed.

fn estimated_state_size(&self) -> usize

Get estimated state size for migration planning.
