Struct Stats 

pub struct Stats {
    pub nodes_live: usize,
    pub nodes_tombstoned: usize,
    pub edges: u64,
    pub rules: Vec<RuleStats>,
    pub chain_truncations: u64,
    pub history_floor: u64,
    pub namespaces: Vec<NamespaceStats>,
}

Database-wide counters plus per-rule budget/fire stats.

Fields

nodes_live: usize

nodes_tombstoned: usize

edges: u64

rules: Vec<RuleStats>

chain_truncations: u64

How many writes hit the rule-chaining depth cap with work still pending, since this handle was opened. Non-zero means some derived edges beyond the cap are stale and no single later write will repair them: split the rule chain or shorten it. Never persisted, so it resets on reopen.

history_floor: u64

The oldest commit index history still reaches (the WAL horizon floor). 0 means nothing has been pruned and history is complete; a non-zero value means events before that commit were pruned and are gone.

namespaces: Vec<NamespaceStats>

Live node counts per namespace, in name order. Always carries default — a store is at least its default namespace — so a single-tenant store reads [{"name":"default", …}] and a reader can tell “no namespaces in use” from one entry.

Trait Implementations
