Enum CollectionDataModel 

pub enum CollectionDataModel {
    Transactional,
    Queue,
    Audit,
    Config,
    Vault,
    Ephemeral,
    Cache,
}

The durability model a collection declares for itself. The first five are durable models whose data must survive a single-node loss; the last two are explicitly local-eligible — losing their most recent unreplicated writes on failover is an accepted trade for lower write latency.

Variants

Transactional

Durable transactional records — the default model for user data.

Queue

Durable work-queue collection (at-least-once delivery semantics).

Audit

Append-only audit log.

Config

Cluster/application configuration.

Vault

Secret/credential material.

Ephemeral

Explicitly ephemeral data with no durability expectation.

Cache

Cache-like data that can be rebuilt from a source of truth.

Implementations

impl CollectionDataModel

pub fn is_durable(self) -> bool

true for models whose data must survive a single-node loss and so may never silently acknowledge a write locally under declared HA intent.

pub fn allows_ephemeral_local(self) -> bool

true for the explicitly local-eligible models (Ephemeral, Cache) that may opt into local commit even under declared HA intent.

pub fn label(self) -> &'static str

Trait Implementations

impl Clone for CollectionDataModel

fn clone(&self) -> CollectionDataModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CollectionDataModel

impl Debug for CollectionDataModel

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

Formats the value using the given formatter.

impl Eq for CollectionDataModel

impl PartialEq for CollectionDataModel

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