Struct SnapshotRecord 

pub struct SnapshotRecord {
    pub aggregate_type: String,
    pub aggregate_id: String,
    pub version: u64,
    pub snapshot_type: String,
    pub snapshot_version: u64,
    pub payload_codec: String,
    pub payload_codec_version: u16,
    pub payload: Vec<u8>,
    pub metadata: HashMap<String, String>,
    pub recorded_at: SystemTime,
}

Stored aggregate snapshot cache record.

This is a repository-owned cache envelope, not an aggregate event and not the user-defined state snapshot payload itself. The payload bytes usually come from Snapshottable::create_snapshot().

Fields

aggregate_type: String

aggregate_id: String

version: u64

Aggregate event sequence covered by this cache record.

snapshot_type: String

snapshot_version: u64

payload_codec: String

payload_codec_version: u16

payload: Vec<u8>

metadata: HashMap<String, String>

recorded_at: SystemTime

Implementations

impl SnapshotRecord

pub const DEFAULT_SNAPSHOT_VERSION: u64 = 1

pub fn new( aggregate_type: impl Into<String>, aggregate_id: impl Into<String>, version: u64, snapshot_type: impl Into<String>, snapshot_version: u64, payload: Vec<u8>, ) -> Self

pub fn validate_for_identity( &self, identity: &StreamIdentity, ) -> Result<(), RepositoryError>

pub fn validate(&self) -> Result<(), RepositoryError>

pub fn has_supported_payload_codec(&self) -> bool

Trait Implementations

impl Clone for SnapshotRecord

fn clone(&self) -> SnapshotRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotRecord

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

Formats the value using the given formatter.

impl PartialEq for SnapshotRecord

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