    ) -> Result<Checkpoint> { ... }
}

Trait for kernels that support checkpointing.

Required Methods

fn create_checkpoint(&self) -> Result<Checkpoint>

Create a checkpoint of the current kernel state.

This should pause the kernel, serialize all state, and return a checkpoint.

fn restore_from_checkpoint(&mut self, checkpoint: &Checkpoint) -> Result<()>

Restore kernel state from a checkpoint.

This should pause the kernel, deserialize state, and resume.

fn checkpoint_kernel_id(&self) -> &str

Get the kernel ID for checkpointing.

fn checkpoint_kernel_type(&self) -> &str

Get the kernel type for checkpointing.

Provided Methods

fn supports_incremental(&self) -> bool

Check if the kernel supports incremental checkpoints.

fn create_incremental_checkpoint( &self, _base: &Checkpoint, ) -> Result<Checkpoint>

Create an incremental checkpoint (only changed state since last checkpoint).
