Struct QueryPlan 

pub struct QueryPlan { /* private fields */ }

Language-neutral executable query plan.

Implementations

impl QueryPlan

pub fn new(operation: QueryOperation, resource: impl Into<String>) -> Self

Starts a plan for operation over the canonical resource name.

pub fn add_projection(&mut self, field: impl Into<String>)

Appends a canonical field to the response projection.

pub fn set_filter(&mut self, filter: QueryFilter)

Replaces the boolean filter.

pub fn add_order(&mut self, order: QueryOrder)

Appends an ordering entry.

pub const fn set_pagination(&mut self, limit: Option<u64>, offset: Option<u64>)

Sets result pagination.

pub fn add_group_by(&mut self, field: impl Into<String>)

Appends a canonical grouping field.

pub fn add_aggregate(&mut self, aggregate: QueryAggregate)

Appends an aggregate projection.

pub fn set_mutation_value( &mut self, field: impl Into<String>, value: QueryValue, )

Sets a canonical mutation assignment.

pub fn add_source_evidence(&mut self, evidence: QuerySourceEvidence)

Attaches source evidence to the plan.

pub const fn operation(&self) -> QueryOperation

Operation.

pub fn resource(&self) -> &str

Canonical resource name.

pub fn projection(&self) -> &[String]

Canonical projected fields in response order.

pub const fn filter(&self) -> Option<&QueryFilter>

Boolean filter.

pub fn order(&self) -> &[QueryOrder]

Ordering entries.

pub const fn limit(&self) -> Option<u64>

Maximum result count.

pub const fn offset(&self) -> Option<u64>

Result offset.

pub fn group_by(&self) -> &[String]

Canonical grouping fields.

pub fn aggregates(&self) -> &[QueryAggregate]

Aggregate projections.

pub const fn mutation(&self) -> &BTreeMap<String, QueryValue>

Canonical mutation assignments.

pub fn source_evidence(&self) -> &[QuerySourceEvidence]

Source ranges retained by the frontend adapter.

pub const fn authorization(&self) -> QueryAuthorization

Lowering validates meaning but never authorizes execution.

pub fn canonical_value(&self) -> Value

Returns the provenance-free canonical JSON value used to compare plans produced by different query languages.

pub fn canonical_json(&self) -> String

Deterministic provenance-free serialization for cross-frontend conformance checks.

Trait Implementations

impl Clone for QueryPlan

fn clone(&self) -> QueryPlan

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryPlan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for QueryPlan

fn eq(&self, other: &QueryPlan) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
