Struct TokioRuntimeLoadSignal 

pub struct TokioRuntimeLoadSignal { /* private fields */ }

Detects Tokio executor load by measuring stable-API timer scheduling lag.

This deliberately uses timer lag instead of the unstable Tokio runtime metrics sketched in INTERFACE.md section 13, so it does not require tokio_unstable.

Implementations

impl TokioRuntimeLoadSignal

pub fn new(options: TokioRuntimeLoadSignalOptions) -> Self

Creates a Tokio runtime load signal with the supplied options.

Trait Implementations

impl Default for TokioRuntimeLoadSignal

fn default() -> Self

Returns the “default value” for a type.

impl LoadSignal for TokioRuntimeLoadSignal

fn overload_threshold(&self) -> f32

Returns the lag-to-sampling-interval ratio as informational metadata.

SystemStatus consumes recorded overload flags directly rather than interpreting this value.

fn name(&self) -> &str

Returns the stable name of this signal.

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Starts any sampling work required by this signal.

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), CrawlError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stops any sampling work required by this signal.

fn sample(&self, window: Duration) -> Vec<LoadSnapshot>

Returns observations from the requested recent window.
