Struct PersistedChangeBatch 

pub struct PersistedChangeBatch { /* private fields */ }

Change batch persisted before its following cursor becomes active.

Implementations

impl PersistedChangeBatch

pub const fn new( id: ChangeBatchId, scope: CloudScope, base_cursor: Option<ChangeCursor>, batch: ChangeBatch, ) -> Self

Creates the first durable form of a fetched change batch.

pub const fn id(&self) -> &ChangeBatchId

Returns the batch identity.

pub const fn scope(&self) -> &CloudScope

Returns the namespace/root checkpoint scope.

pub const fn base_cursor(&self) -> Option<&ChangeCursor>

Returns the active cursor from which this batch was fetched.

pub const fn batch(&self) -> &ChangeBatch

Returns the durable backend batch.

pub const fn state(&self) -> PersistedChangeBatchState

Returns whether replay prerequisites are durable.

pub fn mark_effects_replayable(&mut self) -> bool

Marks the batch effects replayable. The operation is idempotent.

Trait Implementations

impl Clone for PersistedChangeBatch

fn clone(&self) -> PersistedChangeBatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PersistedChangeBatch

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

Formats the value using the given formatter.

impl PartialEq for PersistedChangeBatch

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