Struct PeakEwmaDiscover

pub struct PeakEwmaDiscover<D, C = CompleteOnResponse> { /* private fields */ }

Wraps a D-typed stream of discovered services with PeakEwma.

Implementations

impl<D, C> PeakEwmaDiscover<D, C>

fn new<Request>(discover: D, default_rtt: Duration, decay: Duration, completion: C) -> Self
where
    D: Discover,
    D::Service: Service<Request>,
    C: TrackCompletion<Handle, <D::Service as Service<Request>>::Response>,

Wraps a D-typed Discover so that services have a PeakEwma load metric.

The provided default_rtt is used as the default RTT estimate for newly added services.

They decay value determines over what time period a RTT estimate should decay.
