Enum Lifecycle 

pub enum Lifecycle {
    Pending,
    Running,
    Suspending,
    Suspended,
    Terminating,
    Terminated,
}

The symspec’s vm_state, verbatim.

Six states and no others, which is the S1 half of this module: a lifecycle held as a String would let "RUNNING " and "Running" both exist, and every guard below would have to decide which it meant.

Variants

Pending

The initial state, and the state a launch is accepted into (STATE-1).

Running

The service reports RUNNING; launch has completed bootstrap, or adoption supplied the existing token (STATE-2).

Suspending

A suspend was accepted and the platform has not yet reported it complete (STATE-4).

Suspended

The platform reported suspension complete (STATE-6).

Terminating

A terminate was accepted (STATE-9).

Terminated

The platform reported termination complete (STATE-10).

Implementations

impl Lifecycle

pub fn as_str(self) -> &'static str

The name the service uses for this state, which is also what an error message says.

pub fn from_service(state: &str) -> Option<Lifecycle>

The lifecycle the service’s state names, or None for a spelling this client does not know. constants::MICROVM_STATES is the closed set, and a test ties the two.

pub fn is_live(self) -> bool

Whether a VM in this state is still billing, which is what a Drop warning is for.
