Struct ExplainPlan 

pub struct ExplainPlan { /* private fields */ }

ExplainPlan

Stable, deterministic representation of a planned query for observability.

Implementations

impl ExplainPlan

pub const fn mode(&self) -> QueryMode

Return query mode projected by this explain plan.

pub const fn access(&self) -> &ExplainAccessPath

Borrow projected access-path shape.

pub const fn access_decision(&self) -> &ExplainAccessDecisionV1

Borrow the structured planner access-decision projection.

pub fn filter_expr(&self) -> Option<&str>

Borrow projected semantic scalar filter expression when present.

pub const fn predicate(&self) -> &ExplainPredicate

Borrow projected predicate shape.

pub const fn order_by(&self) -> &ExplainOrderBy

Borrow projected ORDER BY shape.

pub const fn distinct(&self) -> bool

Return whether DISTINCT is enabled.

pub const fn grouping(&self) -> &ExplainGrouping

Borrow projected grouped-shape metadata.

pub const fn order_pushdown(&self) -> &ExplainOrderPushdown

Borrow projected ORDER pushdown status.

pub const fn page(&self) -> &ExplainPagination

Borrow projected pagination status.

pub const fn delete_limit(&self) -> &ExplainDeleteLimit

Borrow projected delete-limit status.

pub const fn consistency(&self) -> MissingRowPolicy

Return missing-row consistency policy.

impl ExplainPlan

pub fn render_text_canonical(&self) -> String

Render this logical explain plan as deterministic canonical text.

This surface is frontend-facing and intentionally stable for SQL/CLI explain output and snapshot-style diagnostics.

pub fn render_json_canonical(&self) -> String

Render this logical explain plan as canonical JSON.

impl ExplainPlan

pub fn fingerprint(&self) -> PlanFingerprint

Compute a stable fingerprint for this explain plan.

impl ExplainPlan

pub fn continuation_signature( &self, entity_path: &'static str, ) -> ContinuationSignature

Compute the continuation signature for this explain plan.

Included fields:

• entity path
• mode (load/delete)
• access path
• canonical scalar semantic filter (filter_expr when present, otherwise predicate)
• canonical order-by (including implicit PK tie-break)
• distinct flag
• grouped shape (group keys, aggregate terminals, grouped limits)
• projection identity section (semantic projection hash when available)

Excluded fields:

• pagination window (limit, offset)
• delete limits
• cursor boundary/token state

Trait Implementations

impl Clone for ExplainPlan

fn clone(&self) -> ExplainPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplainPlan

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

Formats the value using the given formatter.

impl Eq for ExplainPlan

impl PartialEq for ExplainPlan

fn eq(&self, other: &ExplainPlan) -> 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.
