Struct ExecutionSnapshot 

pub struct ExecutionSnapshot {
    pub execution_id: ExecutionId,
    pub tenant_id: TenantId,
    pub user_id: Option<UserId>,
    pub state: ExecutionState,
    pub current_step_id: Option<StepId>,
    pub step_outputs: HashMap<StepId, Value>,
    pub variables: HashMap<String, Value>,
    pub timestamp: DateTime<Utc>,
    pub sequence_number: u64,
}

Execution state snapshot

This captures the current state of an execution for fast resumption. The sequence_number should match the EventStore sequence to verify freshness.

Fields

execution_id: ExecutionId

The execution this snapshot is for

tenant_id: TenantId

Tenant for multi-tenancy isolation

user_id: Option<UserId>

User who initiated this execution (for observability)

state: ExecutionState

Current execution state

current_step_id: Option<StepId>

Currently executing step (if any)

step_outputs: HashMap<StepId, Value>

Outputs from completed steps

variables: HashMap<String, Value>

Working variables

timestamp: DateTime<Utc>

When this snapshot was created

sequence_number: u64

EventStore sequence number at snapshot time

Used to verify freshness - if EventStore has more events, the snapshot may be stale.

Implementations

impl ExecutionSnapshot

pub fn new( execution_id: ExecutionId, tenant_id: TenantId, state: ExecutionState, sequence_number: u64, ) -> Self

Create a new snapshot

pub fn with_user( execution_id: ExecutionId, tenant_id: TenantId, user_id: Option<UserId>, state: ExecutionState, sequence_number: u64, ) -> Self

Create a new snapshot with user_id

pub fn is_fresh(&self, event_store_sequence: u64) -> bool

Check if this snapshot is fresh compared to an EventStore sequence
