Struct ExecutionMetrics 

pub struct ExecutionMetrics { /* private fields */ }

ExecutionMetrics

Compact execution metrics projection derived from one ExecutionTrace. This surface is intentionally small and stable for pre-EXPLAIN observability.

Implementations

impl ExecutionMetrics

pub const fn rows_scanned(&self) -> u64

Return number of rows scanned.

pub const fn rows_materialized(&self) -> u64

Return number of rows materialized.

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.

Trait Implementations

impl Clone for ExecutionMetrics

fn clone(&self) -> ExecutionMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionMetrics

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

Formats the value using the given formatter.

impl PartialEq for ExecutionMetrics

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