Struct OwnDemand 

pub struct OwnDemand;

Every policy’s demand is its own reading: no coordinator places runners.

Trait Implementations

impl Clone for OwnDemand

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OwnDemand

impl Debug for OwnDemand

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

Formats the value using the given formatter.

impl Default for OwnDemand

fn default() -> Self

Returns the “default value” for a type.

impl DemandDirector for OwnDemand

fn directed_demand(&self, _policy: &ScalePolicy) -> Option<u32>

Some(n): policy’s demand this pass is n, not its reading. None: its own reading, as without a coordinator.

fn launched(&self, _policy: &ScalePolicy, _attempt: AttemptId)

A runner was started for policy (as soon as it exists, whether or not its demand was directed).

fn start_failed(&self, _policy: &ScalePolicy, _attempt: Option<AttemptId>)

No runner could be started for policy, for a real reason: not a runner still being brought up. attempt is the one reported through Self::launched whose bring-up failed, if it got that far: what it was reported for is waiting again, to be retried rather than placed anew.

fn older_waiting(&self, _policy: &ScalePolicy) -> bool

Whether an older launch of another policy on this host still has no runner, so policy should let its target’s loop reserve first.
