Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fixed_concurrency: Option<usize>

Pins concurrency and disables all autoscaling when set.

min_concurrency: usize

Minimum dynamic concurrency.

max_concurrency: usize

Maximum dynamic concurrency.

desired_concurrency: Option<usize>

Initial desired concurrency, or the minimum when omitted.

scale_up_step_ratio: f32

Proportional increase applied by load-signal scaling.

scale_down_step_ratio: f32

Proportional decrease applied by load-signal scaling.

desired_utilization_ratio: f32

Mean healthy-history ratio required to scale up.

task_timeout: Option<Duration>

Optional deadline applied to each dispatched request attempt.

max_tasks_per_minute: Option<u32>

Optional global task-start budget per minute.

same_domain_delay: Duration

Minimum delay between reservations for the same host.

maybe_run_interval: Duration

Dispatcher fallback tick for reconsidering whether more work can run.

autoscale_interval: Duration

Interval between load-signal scaling decisions.

mode: AutoscaleMode

Concurrency scaling strategy.

snapshotter: SnapshotterOptions

Load-signal collection configuration.

system_status: SystemStatusOptions

Load-history evaluation configuration.
