Struct Snapshot 

pub struct Snapshot {
    pub aggregate_id: String,
    pub aggregate_type: String,
    pub version: i64,
    pub state: Value,
    pub created_at: u64,
}

A point-in-time capture of an aggregate’s state.

Fields

• aggregate_id: instance the snapshot belongs to
• aggregate_type: type name (e.g., “User”), mirrors Event::aggregate_type
• version: sequence of the last event folded into state; a loader replays events from version + 1 onward
• state: aggregate state serialized by Aggregate::to_snapshot, opaque here
• created_at: wall-clock capture time (milliseconds since UNIX epoch, same unit as Event::timestamp)

Fields

aggregate_id: String

aggregate_type: String

version: i64

state: Value

created_at: u64

Implementations

impl Snapshot

pub fn new( aggregate_id: impl Into<String>, aggregate_type: impl Into<String>, version: i64, state: Value, ) -> Self

Capture a snapshot, stamping created_at with the current wall clock.
