Struct ExecutionScope 

pub struct ExecutionScope {
    pub tenant_id: TenantId,
    pub user_id: UserId,
    pub session_id: SessionId,
    pub thread_id: ThreadId,
    pub task_id: Option<TaskId>,
}

Execution scope — flows through every storage operation.

Isolation rules:

• tenant_id: complete isolation. Tenant A never sees Tenant B.
• user_id: within tenant, users share collective but not private memory.
• session_id: within user, sessions share long-term memory but not in-progress state.
• thread_id: within session, threads are independent conversations.
• task_id: within thread, tasks track specific work items.

Fields

tenant_id: TenantId

user_id: UserId

session_id: SessionId

thread_id: ThreadId

task_id: Option<TaskId>

Implementations

impl ExecutionScope

pub fn new( tenant_id: impl Into<String>, user_id: impl Into<String>, session_id: impl Into<String>, thread_id: impl Into<String>, ) -> Self

pub fn with_task(self, task_id: impl Into<String>) -> Self

pub fn namespace(&self) -> &str

SurrealDB namespace for this scope — tenant-level isolation.

Maps to db.use_ns(scope.namespace()). Each tenant gets a separate SurrealDB namespace — complete isolation at the storage layer. No query can cross namespace boundaries.

Used by SurrealCheckpointer at construction time and by SurrealMemoryStore per-call via scoped().

pub fn database(&self) -> &str

Database name within the namespace.

Maps to db.use_db(scope.database()). Fixed per deployment — all agents share one database within a tenant namespace. Table-level scoping (thread_id, user_id, session_id) provides finer isolation within the database.

Trait Implementations
