Struct FluentDeleteQuery 

pub struct FluentDeleteQuery<'a, E>
where
    E: EntityKind,
{ /* private fields */ }

FluentDeleteQuery

Session-bound delete query wrapper. This type owns intent construction and execution routing only. All result projection and cardinality handling lives on Response<E>.

Implementations

impl<'a, E> FluentDeleteQuery<'a, E>

where E: EntityKind,

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

pub fn by_id(self, id: Id<E>) -> Self

Set the access path to a single typed primary-key value.

Id<E> is treated as a plain query input value here. It does not grant access.

pub fn by_ids<I>(self, ids: I) -> Self

where I: IntoIterator<Item = Id<E>>,

Set the access path to multiple typed primary-key values.

IDs are public and may come from untrusted input sources.

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

pub fn filter_expr(self, expr: FilterExpr) -> Result<Self, QueryError>

pub fn sort_expr(self, expr: SortExpr) -> Result<Self, QueryError>

pub fn order_by(self, field: impl AsRef<str>) -> Self

pub fn order_by_desc(self, field: impl AsRef<str>) -> Self

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

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

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

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

where E: EntityValue,

Execute this delete using the session’s policy settings.

All result inspection and projection is performed on Response<E>.

pub fn is_empty(&self) -> Result<bool, QueryError>

where E: EntityValue,

Execute and return whether any rows were affected.

pub fn count(&self) -> Result<u32, QueryError>

where E: EntityValue,

Execute and return the number of affected rows.

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

where E: EntityValue,

Execute and require exactly one affected row.

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

where E: EntityValue,

Execute and require at least one affected row.

impl<E> FluentDeleteQuery<'_, E>

where E: EntityKind + SingletonEntity, E::Key: Default,

pub fn only(self) -> Self

Delete the singleton entity.
