Struct ReadTransaction 

pub struct ReadTransaction<'db, S: Schema> { /* private fields */ }

One client-owned reusable read transaction over a schema-bound database.

Query sessions borrow this wrapper and execute every terminal on its one retained read context. Closing consumes the wrapper without commit semantics; dropping an open wrapper likewise cannot commit.

Implementations

impl<'db, S: Schema> ReadTransaction<'db, S>

pub fn entities<M>(&self) -> ReadEntityManager<'_, S, M>

where M: EntityModel<Schema = S> + CompleteModel,

Create a read-only exact entity manager borrowing this transaction. Every derived filter terminal reuses the retained read context.

pub fn relations<M>(&self) -> ReadRelationManager<'_, S, M>

where M: RelationModel<Schema = S> + CompleteModel,

Create a read-only exact relation manager borrowing this transaction. Every derived filter terminal reuses the retained read context.

pub fn query(&self) -> QuerySession<'_, S>

Start one owner-branded query session borrowing this read context.

pub fn query_with_resources( &self, resources: QueryExecutionResourceLimits, cancellation: AnswerCancellation, ) -> QuerySession<'_, S>

Start one borrowed query session with one common tighten-only resource policy and caller-owned cooperative cancellation signal.

pub async fn close(self) -> Result<()>

Close this read transaction without committing.
