Struct UsageLedger 

pub struct UsageLedger {
    pub servers: BTreeMap<String, ServerUsage>,
}

The on-disk usage ledger (<data_dir>/addons/usage.json).

Fields

servers: BTreeMap<String, ServerUsage>

Per-server usage, keyed by gateway server name (the addon slug).

Implementations

impl UsageLedger

pub fn load() -> Self

Load the ledger, or an empty one if it does not exist / is unreadable.

pub fn save(&self) -> Result<(), String>

Persist the ledger (creating the addons/ dir as needed).

pub fn record_into(&mut self, server: &str, tool: &str, ok: bool)

Apply one call to the in-memory ledger. Pure — the unit-testable core of record.

pub fn by_usage(&self) -> Vec<(&String, &ServerUsage)>

Servers sorted by total calls (descending) — the “most-used” ordering for discovery / dashboards. Ties broken by name for determinism.
