Struct RuleVersionHistory 

struct RuleVersionHistory {
    versions: Vec<CompiledRule>,
    active_version: Option<u64>,
    status_by_version: HashMap<u64, RuleStatus>,
    registered_at: HashMap<u64, SystemTime>,
}

Per-rule version history and status tracking.

Fields

versions: Vec<CompiledRule>

Versions ordered by the registry’s insertion order (FIFO). The oldest entry is evicted first when we exceed max_history.

active_version: Option<u64>

Currently active version (if any).

status_by_version: HashMap<u64, RuleStatus>

Lifecycle status per version.

registered_at: HashMap<u64, SystemTime>

When each version was registered.

Implementations

impl RuleVersionHistory

fn new() -> Self

fn insert_version(&mut self, rule: CompiledRule, max_history: usize)

Insert a new version. Does not touch status — the caller sets it. Evicts the oldest version if we exceed max_history.

fn get(&self, version: u64) -> Option<&CompiledRule>

fn active(&self) -> Option<&CompiledRule>
