Checkpoint

Trait Checkpoint 

Source
pub trait Checkpoint: Send + Sync {
    // Required method
    fn checkpoint<'life0, 'life1, 'async_trait>(
        &'life0 self,
        dst: &'life1 Path,
        opts: CheckpointOptions,
    ) -> Pin<Box<dyn Future<Output = Result<CheckpointImage>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}
Expand description

Capture the VM’s state to disk.

Quiescing is this capability’s own business: the driver freezes the guest for the capture and, per CheckpointOptions::after, either resumes it or leaves it crate::VmState::Quiesced. There is no pause verb on the handle.

Required Methods§

Source

fn checkpoint<'life0, 'life1, 'async_trait>( &'life0 self, dst: &'life1 Path, opts: CheckpointOptions, ) -> Pin<Box<dyn Future<Output = Result<CheckpointImage>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Writes a checkpoint of the VM into dst (created if missing).

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
