Struct ActiveSubscription 

pub struct ActiveSubscription {
    pub id: SubscriptionId,
    pub subscription_name: String,
    pub definition: SubscriptionDefinition,
    pub user_context: Value,
    pub variables: Value,
    pub created_at: DateTime<Utc>,
    pub connection_id: String,
    pub rls_conditions: Vec<(String, Value)>,
}

A client’s active subscription.

Fields

id: SubscriptionId

Unique subscription ID.

subscription_name: String

Subscription type name from schema.

definition: SubscriptionDefinition

Reference to subscription definition.

user_context: Value

User context for authorization filtering.

variables: Value

Runtime variables provided by client.

created_at: DateTime<Utc>

When the subscription was created.

connection_id: String

Connection/client identifier (for routing).

rls_conditions: Vec<(String, Value)>

Row-level security conditions evaluated at subscribe time.

Each entry is (field_path, expected_value). An event is only delivered when every condition matches the event data (AND semantics). An empty list means no RLS filtering (admin or no RLS policy).

Implementations

impl ActiveSubscription

pub fn new( subscription_name: impl Into<String>, definition: SubscriptionDefinition, user_context: Value, variables: Value, connection_id: impl Into<String>, ) -> Self

Create a new active subscription.

Arguments

• subscription_name - Schema subscription name
• definition - Subscription definition from compiled schema
• user_context - Raw user context JSON from WebSocket connection_init
• variables - Runtime variables from client
• connection_id - Client connection identifier

pub fn with_rls_conditions(self, conditions: Vec<(String, Value)>) -> Self

Set row-level security conditions for event filtering.

The caller evaluates the RLS policy against the user’s SecurityContext at subscribe time and converts the resulting WhereClause into (field, value) equality conditions. During event delivery, matches_subscription checks every condition against the event data.
