Struct SnapshotEngine 

pub struct SnapshotEngine { /* private fields */ }

Snapshot Engine - Builds memory snapshots from event data

The SnapshotEngine is responsible for constructing point-in-time views of memory usage from the events stored in the EventStore.

Key properties:

• Read-only: Does not consume events from EventStore
• Efficient: Optimized for fast snapshot construction
• Comprehensive: Captures all relevant memory state

Implementations

impl SnapshotEngine

pub fn new(event_store: SharedEventStore) -> Self

Create a new SnapshotEngine

pub fn build_snapshot(&self) -> MemorySnapshot

Build a snapshot from the current event store state

This method reads all events from the event store and constructs a snapshot representing the current memory state.

pub fn build_snapshot_from_events( &self, events: &[MemoryEvent], ) -> MemorySnapshot

Build a snapshot from a specific set of events

This method accepts a slice reference to avoid unnecessary cloning. The caller retains ownership of the events vector.

Arguments

• events - A slice of events to build the snapshot from

Example

let events = vec![MemoryEvent::allocate(0x1000, 64, 1)];
let snapshot = engine.build_snapshot_from_events(&events);
// events is still available here

pub fn event_store(&self) -> &SharedEventStore

Get the event store reference
