Enum PolicyLifecycle 

pub enum PolicyLifecycle {
    Loaded(CompiledId),
    Superseded(CompiledId),
    Removed(CompiledId),
}

A policy-lifecycle event, parallel to Lifecycle but scoped to a compiled artifact rather than an account. Without it, an evaluator that accumulates state per compiled policy (a cache, a counter) has no way to learn that one of its artifacts no longer corresponds to anything the tree will ever route to again, and keeps it forever.

Delivery is not reliable, and does not need to be: a caller who never sends Removed for a policy that stopped existing has left an evaluator holding a stale artifact, but the tree this crate builds decides what is routed anywhere – a stale artifact nothing routes to is a memory leak, never a correctness problem. See plan/policy.md’s “a missed removal is inert, not dangerous.” Do not build retry or acknowledgement machinery for this channel.

Variants

Loaded(CompiledId)

compile produced this artifact and it is now (or remains) the one a tree may route decisions to.

Superseded(CompiledId)

A newer compile of the same logical policy succeeded, and this artifact is no longer the one any tree routes to – safe to drop. Never sent when a newer revision failed to compile: didbot-pds’s loader keeps routing to the last-good artifact in that case, so it is very much still in use – see plan/policy.md’s last-good- revision behaviour.

Removed(CompiledId)

The record this artifact was compiled from is gone from every source – deleted, or never re-observed after a source’s own failure recovered onto a view that no longer names it. Safe to drop.

Trait Implementations

impl Clone for PolicyLifecycle

fn clone(&self) -> PolicyLifecycle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyLifecycle

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

Formats the value using the given formatter.

impl PartialEq for PolicyLifecycle

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