WaitOpts

Struct WaitOpts 

Source
pub struct WaitOpts {
    pub timeout: Duration,
    pub poll_interval: Duration,
    pub stall_grace: Duration,
}
Expand description

How long to wait and how often to poll.

Fields§

§timeout: Duration

The client-side deadline.

§poll_interval: Duration

The gap between polls.

§stall_grace: Duration

How long CREATING is tolerated before the stall probe runs (TRAP-2).

Only meaningful for the image wait; the launch wait has no equivalent, because a launch has no build list to probe.

Implementations§

Source§

impl WaitOpts

Source

pub fn for_launch() -> Self

Options for the launch wait: crate::sandbox::DEFAULT_LIFECYCLE_TIMEOUT at crate::sandbox::LIFECYCLE_POLL_INTERVAL, five minutes at five-second polls.

Source

pub fn for_lifecycle(timeout: Duration) -> Self

Options for a lifecycle wait (a launch, suspend, resume or terminate) with the caller’s deadline: core’s crate::sandbox::LIFECYCLE_POLL_INTERVAL, and no stall probe.

Every surface’s lifecycle wait starts here, so what a lifecycle wait is lives in one place (#266); a caller that polls at another rate sets poll_interval on the result. stall_grace is set past any deadline rather than to zero, since a zero grace would read as “probe immediately”, and a lifecycle transition has no build list to probe (TRAP-2 is the image build’s).
