Enum Outcome 

#[non_exhaustive]
pub enum Outcome {
    Success {
        rtt: Duration,
    },
    Failure,
}

Available on crate feature adaptive only.

The observed result of one completed request, fed back to the strategy.

#[non_exhaustive]: more signals may be added.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Success

The request succeeded, with this round-trip time. Latency-based strategies use the timing; count-based ones treat it as a plain success.

Fields

rtt: Duration

Measured round-trip time of the request.

Failure

The request failed (an error, a timeout, or a downstream rejection) — a signal to back off.

Trait Implementations

impl Clone for Outcome

fn clone(&self) -> Outcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Outcome

impl Debug for Outcome

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

Formats the value using the given formatter.

impl Eq for Outcome

impl PartialEq for Outcome

fn eq(&self, other: &Outcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
