Struct CrunHandler 

pub struct CrunHandler { /* private fields */ }

Owns both the foreground crun run process and the OCI runtime state. Lifecycle operations always target the container ID through crun; merely signalling the wrapper process is never treated as cleanup. Dropping the in-process handle deliberately detaches without destroying the workload so short-lived CLI commands can launch persistent boxes. Explicit lifecycle operations and crash reconciliation own runtime cleanup.

Trait Implementations

impl VmHandler for CrunHandler

fn stop(&mut self, signal: i32, timeout_ms: u64) -> Result<()>

Stop the VM. Sends signal first, then SIGKILL after timeout_ms.

fn metrics(&self) -> VmMetrics

Get current CPU and memory metrics.

fn is_running(&self) -> bool

Check if the VM process is still alive.

fn has_exited(&self) -> bool

Whether the VM process has exited, treating a zombie (an exited child not yet reaped by its parent) as exited.

fn pid(&self) -> u32

Return the OS process ID of the VM.

fn exit_code(&self) -> Option<i32>

Return the exit code of the VM process, if it has exited.

fn try_wait_exit(&mut self) -> Result<Option<i32>>

Poll the VM process for natural exit without sending any signal.
