Struct datafusion_physical_plan::metrics::ExecutionPlanMetricsSet

pub struct ExecutionPlanMetricsSet { /* private fields */ }

A set of Metrics for an individual “operator” (e.g. &dyn ExecutionPlan).

This structure is intended as a convenience for ExecutionPlan implementations so they can generate different streams for multiple partitions but easily report them together.

Each clone() of this structure will add metrics to the same underlying metrics set

Implementations

impl ExecutionPlanMetricsSet

pub fn new() -> Self

Create a new empty shared metrics set

pub fn register(&self, metric: Arc<Metric>)

Add the specified metric to the underlying metric set

pub fn clone_inner(&self) -> MetricsSet

Return a clone of the inner MetricsSet

Trait Implementations

impl Clone for ExecutionPlanMetricsSet

fn clone(&self) -> ExecutionPlanMetricsSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionPlanMetricsSet

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

Formats the value using the given formatter.

impl Default for ExecutionPlanMetricsSet

fn default() -> ExecutionPlanMetricsSet

Returns the “default value” for a type.
