Struct RollbackOutcome 

pub struct RollbackOutcome {
    pub recovered_to_lsn: u64,
    pub tail_lsns: u64,
    pub rollback_file: Option<String>,
    pub event_fired: bool,
    pub role: NodeRole,
}

The result of a completed rejoin.

Fields

recovered_to_lsn: u64

The LSN the node recovered to — the common point.

tail_lsns: u64

Number of LSNs removed from the live timeline (0 when there was no divergent tail).

rollback_file: Option<String>

Where the discarded tail was preserved. None only when there was no tail to preserve.

event_fired: bool

Whether the loud operator event fired. Always true when a tail was discarded; false for a clean rejoin with no tail.

role: NodeRole

The role the node now plays — a replica of the new primary under the new term.

Implementations

impl RollbackOutcome

pub fn rolled_back_tail(&self) -> bool

True when a divergent tail was actually rolled back (as opposed to a clean rejoin with nothing to discard).

Trait Implementations

impl Clone for RollbackOutcome

fn clone(&self) -> RollbackOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RollbackOutcome

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

Formats the value using the given formatter.

impl Eq for RollbackOutcome

impl PartialEq for RollbackOutcome

fn eq(&self, other: &RollbackOutcome) -> 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.
