Struct EngineContext 

pub struct EngineContext {
    pub session: Uuid,
    pub transaction: Option<Uuid>,
}

Which session, and which explicit transaction, a request applies to.

Mirrors the RequestContext every request carries in the SurrealDB network protocol, minus the fields the SDK does not populate: an engine applies its own configured timeouts rather than being told them per call.

Fields

session: Uuid

The session the request runs under.

transaction: Option<Uuid>

The explicit transaction to run in, or None for an implicit one.

Only meaningful on SurrealEngine::query; the transaction-lifecycle methods take the transaction they act on as an explicit argument.

Implementations

impl EngineContext

pub fn new(session: Uuid) -> Self

A context for a request outside any explicit transaction.

pub fn with_transaction(session: Uuid, transaction: Option<Uuid>) -> Self

A context for a request inside the given explicit transaction.
