Fields

status: HashMap<String, PingStatus>

has_pinged: bool

generation: u64

slow_threshold_ms: u16

auto_ping: bool

filter_down_only: bool

Implementations

impl PingState

pub fn from_preferences() -> 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.

Trait Implementations

impl Default for PingState

fn default() -> Self

Returns the “default value” for a type.
