Trait tower::load::Load

pub trait Load {
    type Metric: PartialOrd;

    // Required method
    fn load(&self) -> Self::Metric;
}

Available on crate feature load only.

Types that implement this trait can give an estimate of how loaded they are.

See the module documentation for more details.

Required Associated Types

type Metric: PartialOrd

A comparable load metric.

Lesser values indicate that the service is less loaded, and should be preferred for new requests over another service with a higher value.

Required Methods

fn load(&self) -> Self::Metric

Estimate the service’s current load.
