Struct CachedSnapshot 

Source 
pub struct CachedSnapshot {
    pub services: Vec<ServiceInfo>,
    pub refreshed_at: Instant,
}
Expand description

A point-in-time snapshot of all service statuses.

Why: Separating the cached data from the lock makes it cheap to clone the snapshot out of the lock and work with it without holding the lock. What: Contains the service info list (same order as the connector list) and the instant when the poll completed. Test: Constructed by PollerCache::poll_once; inspected by tests below.

Fields§

§services: Vec<ServiceInfo>

Service info for each connector, in connector-list order.

§refreshed_at: Instant

Wall-clock instant when this snapshot was produced. Reserved for future staleness-reporting (P2+); not yet surfaced in the API.

Implementations§

Source§

impl CachedSnapshot

Source

pub fn url_map(&self) -> HashMap<String, String>

Build a URL map from daemon id → base URL for running daemons.

Why: The proxy router needs to resolve a daemon name to its live base URL quickly, without re-scanning the snapshot on every request. What: Iterates services and collects only those with a url. Test: test_snapshot_url_map below.
