Struct ExecutionTrace 

pub struct ExecutionTrace { /* private fields */ }

ExecutionTrace

Structured, opt-in load execution introspection snapshot. Captures plan-shape and execution decisions without changing semantics.

Implementations

impl ExecutionTrace

pub const fn metrics(&self) -> ExecutionMetrics

Return compact execution metrics for pre-EXPLAIN observability surfaces.

pub const fn access_path_variant(&self) -> ExecutionAccessPathVariant

Return the coarse executed access-path variant.

pub const fn direction(&self) -> OrderDirection

Return executed order direction.

pub const fn optimization(&self) -> Option<ExecutionOptimization>

Return selected optimization, if any.

pub const fn keys_scanned(&self) -> u64

Return number of keys scanned.

pub const fn rows_materialized(&self) -> u64

Return number of rows materialized.

pub const fn rows_returned(&self) -> u64

Return number of rows returned.

pub const fn execution_time_micros(&self) -> u64

Return execution time in microseconds.

pub const fn index_only(&self) -> bool

Return whether execution remained index-only.

pub const fn continuation_applied(&self) -> bool

Return whether continuation was applied.

pub const fn index_predicate_applied(&self) -> bool

Return whether index predicate pushdown was applied.

pub const fn index_predicate_keys_rejected(&self) -> u64

Return number of keys rejected by index predicate pushdown.

pub const fn distinct_keys_deduped(&self) -> u64

Return number of deduplicated keys under DISTINCT processing.

Trait Implementations

impl Clone for ExecutionTrace

fn clone(&self) -> ExecutionTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionTrace

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

Formats the value using the given formatter.

impl PartialEq for ExecutionTrace

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