Enum FailoverMode 

pub enum FailoverMode {
    Coordinated {
        catch_up_deadline: Duration,
    },
    Force {
        timeout: Duration,
    },
}

How a failover should be executed.

Variants

Coordinated

Zero-RPO coordinated handover. The target MUST reach the frozen frontier within catch_up_deadline; otherwise the handover aborts and writes resume on the old primary. No acknowledged write is ever lost.

Fields

catch_up_deadline: Duration

Force

Emergency handover. Tries to reach the frontier but completes within timeout regardless, surfacing the skipped catch-up.

Fields

timeout: Duration

Trait Implementations

impl Clone for FailoverMode

fn clone(&self) -> FailoverMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailoverMode

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

Formats the value using the given formatter.

impl PartialEq for FailoverMode

fn eq(&self, other: &FailoverMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
