Enum Staleness 

pub enum Staleness {
    Linearized,
    BestEffort {
        max_lag: Duration,
    },
}

The core’s own types, re-exported: every field of record::ParsedPolicy is one of these, so a caller that declares a policy reaches them through this crate rather than depending on didbot-policy for the names alone. How stale an evaluator’s view of the world may be before it is unhealthy.

Variants

Linearized

Blocks rather than answer from a stale view. Its lag bound is its latency bound, and it is a throughput ceiling — the right choice for a deterministic, in-process evaluator whose answer is exact and cheap.

BestEffort

Answers from what it has seen. Exceeding max_lag is a health failure, routed the same way a crashed evaluator is: the writes the tree scopes to it are refused until it catches up.

Fields

max_lag: Duration

The most this evaluator’s view may lag reality before it counts as unhealthy.

Trait Implementations

impl Clone for Staleness

fn clone(&self) -> Staleness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Staleness

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

Formats the value using the given formatter.

impl PartialEq for Staleness

fn eq(&self, other: &Staleness) -> 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.
