Enum PoolSlot 

pub enum PoolSlot {
    Available {
        snapshot_path: PathBuf,
        mem_file_path: PathBuf,
        vm_id: String,
    },
    InUse {
        cell_id: String,
    },
    Empty,
}

State of one slot in the warm pool.

Variants

Available

Slot has a snapshot on disk and is ready to be checked out.

Fields

snapshot_path: PathBuf

Filesystem path to the Firecracker VM state file written by PUT /snapshot/create. PUT /snapshot/load consumes this as snapshot_path at restore time.

mem_file_path: PathBuf

Filesystem path to the paired memory dump (mem_file_path in the SnapshotCreate body). Required at restore time via the mem_backend.backend_path field on PUT /snapshot/load.

vm_id: String

Stable identifier for the pre-booted VM (used in logs / metrics).

InUse

Slot has been handed to an active cell — not eligible for checkout.

Fields

cell_id: String

Cell id currently holding this slot. Used by checkin to validate the caller is releasing the slot they actually checked out.

Empty

Slot has no snapshot yet (initial state, or post-checkin awaiting background re-fill).

Trait Implementations

impl Clone for PoolSlot

fn clone(&self) -> PoolSlot

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PoolSlot

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PoolSlot

fn eq(&self, other: &PoolSlot) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
