Struct ImmediateDrainConfig 

pub struct ImmediateDrainConfig {
    pub max_zero_timeout_polls_per_burst: usize,
    pub max_burst_duration: Duration,
    pub backoff_timeout: Duration,
}

Immediate event-drain policy for the runtime main loop.

When a poll reports readiness, the runtime drains events by repeatedly checking poll_event(Duration::ZERO) to avoid latency between buffered inputs. This policy bounds that immediate-drain path so bursty workloads do not devolve into zero-timeout spin storms.

Fields

max_zero_timeout_polls_per_burst: usize

Maximum consecutive zero-timeout polls allowed in a single burst window.

max_burst_duration: Duration

Maximum wall-clock time spent in a single immediate-drain burst window.

backoff_timeout: Duration

Non-zero poll timeout used when the burst window budget is exhausted.
