Struct ElasticPool 

pub struct ElasticPool<P: ScalingPolicy> {
    pub nodes: &'static [&'static TaskNode],
    pub min: u8,
    pub max: u8,
    pub policy: P,
}

An elastic pool of single-instance nodes scaled by policy P.

Fields

nodes: &'static [&'static TaskNode]

The pool’s member nodes (each a single-instance OnDemand/Terminate node).

min: u8

Floor — keep at least this many members running.

max: u8

Ceiling — never run more than this many members.

policy: P

The scaling policy driving grow/shrink decisions.

Trait Implementations

impl<P: ScalingPolicy + Sync> Pool for ElasticPool<P>

fn evaluate(&self, now: Instant) -> PoolAction

Run the policy against the current snapshot and report the action to apply. Does not itself start/stop (that’s async — the caller does it).

fn deferred_until(&self) -> Option<Instant>

Earliest instant this pool must be re-evaluated without a signal.

fn members(&self) -> &'static [&'static TaskNode]

The pool’s member nodes (floor first). Used by the supervisor’s control interface to co-control a whole pool from any member, and by a task-state view to group members. This is the single source of pool membership — the same slice the scaling policy iterates.
