Struct FixedController 

pub struct FixedController { /* private fields */ }

Controller that always emits the same configured Decision.

Useful as an explicit opt-out from adaptive control while still wanting a hard cap, and as a regression baseline when comparing adaptive algorithms under the simulator.

Implementations

impl FixedController

pub fn new(decision: Decision) -> Self

pub fn with_concurrency(max_in_flight: u32) -> Self

pub fn with_rate(rate_per_sec: f64) -> Self

pub fn with_concurrency_and_rate(max_in_flight: u32, rate_per_sec: f64) -> Self

Trait Implementations

impl Clone for FixedController

fn clone(&self) -> FixedController

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Controller for FixedController

fn on_sample(&mut self, _sample: &Sample)

Record a completed operation.

fn on_tick(&mut self, _now: Instant) -> Decision

Produce the current decision. Called periodically by the enforcement layer. The controller must return an absolute limit (not a delta).

fn name(&self) -> &'static str

Short, stable identifier used in logs and metrics (e.g. “noop”, “fixed”, “ratio”).

fn snapshot(&self) -> ControllerSnapshot

Snapshot of the controller’s observable state for diagnostics and progress display. Default returns an empty snapshot, which is appropriate for controllers that have no meaningful internal state to surface.

impl Debug for FixedController

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

Formats the value using the given formatter.

impl Copy for FixedController
