Struct PingState 

pub struct PingState { /* private fields */ }

Ping/health-check state for all hosts.

Implementations

impl PingState

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

pub fn status_map_mut(&mut self) -> &mut HashMap<String, PingStatus>

pub fn status_of(&self, alias: &str) -> Option<&PingStatus>

pub fn status_contains(&self, alias: &str) -> bool

pub fn status_len(&self) -> usize

pub fn status_is_empty(&self) -> bool

pub fn insert_status(&mut self, alias: String, status: PingStatus)

pub fn remove_status(&mut self, alias: &str)

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

pub fn last_checked_at(&self, alias: &str) -> Option<&Instant>

pub fn record_check(&mut self, alias: String, at: Instant)

pub fn has_pinged(&self) -> bool

pub fn set_has_pinged(&mut self, value: bool)

pub fn generation(&self) -> u64

pub fn set_generation(&mut self, value: u64)

pub fn slow_threshold_ms(&self) -> u16

pub fn set_slow_threshold_ms(&mut self, value: u16)

pub fn auto_ping(&self) -> bool

pub fn set_auto_ping(&mut self, value: bool)

pub fn filter_down_only(&self) -> bool

pub fn set_filter_down_only(&mut self, value: bool)

pub fn checked_at(&self) -> Option<Instant>

pub fn set_checked_at(&mut self, value: Option<Instant>)

pub fn from_preferences(paths: Option<&Paths>) -> Self

Construct with slow threshold + auto-ping loaded from preferences.

pub fn clear_results(&mut self)

Clear all ping results and reset the dynamic filter/timestamp state. Preserves config (slow_threshold_ms, auto_ping) and has_pinged. Bumps generation so in-flight ping responses can be discarded.

pub fn is_stale(&self, alias: &str) -> bool

True when no ping result exists for alias, or the result is older than STALE_REFRESH_AFTER. Used to decide whether selecting a host should trigger a background refresh.

pub fn prune_orphans(&mut self, valid_aliases: &HashSet<&str>)

Drop status and last_checked entries whose alias is no longer in valid_aliases. Called from App::reload_hosts after the new host list lands so stale ping entries cannot outlive their host.

pub fn migrate_alias(&mut self, old: &str, new: &str)

Move status and last_checked entries from old to new. Called from App::migrate_alias_keyed_caches before reload_hosts, whose prune step would otherwise drop entries still under the old alias. No-op when old == new.

Trait Implementations

impl Default for PingState

fn default() -> Self

Returns the “default value” for a type.
