Struct Transaction 

pub struct Transaction { /* private fields */ }

One in-flight change of the protected headers of a cluster, as the main process sees it. Persistable: see the module documentation.

Implementations

impl Transaction

pub fn begin( journal: &mut ProtectedHeaderJournal, cluster_id: &str, change: ProtectedHeaderChange, workers: impl IntoIterator<Item = WorkerId>, ) -> Result<Self, BeginError>

Propose change for cluster_id and target workers. Refused before the journal is touched when there is no worker.

pub fn cluster_id(&self) -> &str

pub fn version(&self) -> ProtectedHeaderVersion

pub fn phase(&self) -> Phase

pub fn is_finished(&self) -> bool

pub fn workers(&self) -> Vec<WorkerId>

Every targeted worker, in order: the recipients of the prepare order.

pub fn prepared( &mut self, worker: WorkerId, version: ProtectedHeaderVersion, ) -> Step

worker staged version.

pub fn committed( &mut self, journal: &mut ProtectedHeaderJournal, worker: WorkerId, version: ProtectedHeaderVersion, ) -> Step

worker applied version; the last acknowledgement confirms it.

pub fn failed( &mut self, journal: &mut ProtectedHeaderJournal, worker: WorkerId, version: ProtectedHeaderVersion, ) -> Step

worker refused version, or the order to it could not be queued. Before the commit is confirmed that starts the abort of every worker; a failed abort marks the worker as unrecoverable.

pub fn aborted( &mut self, journal: &mut ProtectedHeaderJournal, worker: WorkerId, version: ProtectedHeaderVersion, ) -> Step

worker dropped or undid version.

pub fn timed_out(&mut self, journal: &mut ProtectedHeaderJournal) -> Step

The deadline passed. A transaction not yet aborting starts to abort; one already aborting gives up on the workers that did not answer.
