Struct SessionDeleteQuery 

pub struct SessionDeleteQuery<'a, C: CanisterKind, E: EntityKind<Canister = C>> { /* private fields */ }

SessionDeleteQuery

Fluent, session-bound delete query wrapper that keeps intent pure while routing execution through the DbSession boundary.

Implementations

impl<'a, C: CanisterKind, E: EntityKind<Canister = C>> SessionDeleteQuery<'a, C, E>

pub const fn intent(&self) -> &Query<E>

Return a reference to the underlying intent.

pub fn filter(self, predicate: Predicate) -> Self

Add a predicate, implicitly AND-ing with any existing predicate.

pub fn order_by(self, field: &'static str) -> Self

Append an ascending sort key.

pub fn order_by_desc(self, field: &'static str) -> Self

Append a descending sort key.

pub fn limit(self, limit: u32) -> Self

Apply a delete limit to bound mutation size.

pub fn explain(&self) -> Result<ExplainPlan, QueryError>

Explain this intent without executing it.

pub fn plan(&self) -> Result<ExecutablePlan<E>, QueryError>

Plan this intent into an executor-ready plan.

pub fn execute(&self) -> Result<Response<E>, QueryError>

Execute this intent using the session’s policy settings.

pub fn delete_rows(&self) -> Result<Response<E>, QueryError>
