Enum TwoPhaseState 

pub enum TwoPhaseState {
    Idle,
    Preparing,
    AllPrepared,
    MarkerWritten,
    Committing,
    Committed,
    Aborted,
}

Phase of the 2PC protocol.

Variants

Idle

Initial state: no 2PC in progress.

Preparing

Preparing: writing WAL frames to participant databases.

AllPrepared

All participants have been prepared (WAL frames written + fsynced).

MarkerWritten

Global commit marker has been written.

Committing

Phase 2 in progress: updating WAL-index headers.

Committed

All WAL-index headers updated; 2PC complete.

Aborted

Protocol aborted (either explicitly or due to failure).

Trait Implementations

impl Clone for TwoPhaseState

fn clone(&self) -> TwoPhaseState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TwoPhaseState

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

Formats the value using the given formatter.

impl Hash for TwoPhaseState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TwoPhaseState

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