Trait DowningProvider 

Source 
pub trait DowningProvider:
    Send
    + Sync
    + 'static {
    // Required methods
    fn name(&self) -> &'static str;
    fn should_down(
        &self,
        member: &Member,
        unreachable_for: Duration,
        now: SystemTime,
    ) -> bool;
}
Expand description

Pluggable policy that decides when an unreachable member is down.

v0.10 ships only timeout downing. Quorum and split-brain resolution strategies belong in a later work package before placement relies on automatic downing for singleton safety.

Required Methods§

Source

fn name(&self) -> &'static str

Human-readable provider name for diagnostics.

Source

fn should_down( &self, member: &Member, unreachable_for: Duration, now: SystemTime, ) -> bool

Return true when member should transition to Down.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
