Struct FailureDetectorConfig 

pub struct FailureDetectorConfig {
    pub protocol_period: Duration,
    pub ping_timeout: Duration,
    pub ping_req_count: usize,
    pub suspect_timeout: Duration,
    pub gossip_fanout: usize,
}

Configuration for the SWIM-based failure detector.

Replaces the old simple ping-count model with the full SWIM protocol: protocol periods, indirect pings, suspicion with timeout, and gossip piggybacking.

Fields

protocol_period: Duration

How often the protocol runs a probe cycle.

ping_timeout: Duration

Timeout for a direct ping response.

ping_req_count: usize

Number of random peers to ask for an indirect ping when a direct ping fails.

suspect_timeout: Duration

How long a member stays in “suspect” state before being declared dead.

gossip_fanout: usize

Maximum number of gossip updates piggybacked per protocol message.

Implementations

impl FailureDetectorConfig

pub fn from_legacy( ping_interval: Duration, ping_timeout: Duration, max_missed_pings: u32, ) -> Self

Migrate from the pre-SWIM config fields.

Maps old field names to the SWIM equivalents:

• ping_interval -> protocol_period
• ping_timeout -> ping_timeout (unchanged)
• max_missed_pings -> suspect_timeout (computed as ping_interval * max_missed_pings)

New SWIM-specific fields (ping_req_count, gossip_fanout) use defaults.

Trait Implementations

impl Clone for FailureDetectorConfig

fn clone(&self) -> FailureDetectorConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FailureDetectorConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FailureDetectorConfig

fn default() -> Self

Returns the “default value” for a type.
