Struct opentelemetry::sdk::metrics::aggregators::SumAggregator

pub struct SumAggregator { /* fields omitted */ }

This is supported on crate feature metrics only.

An aggregator for counter events.

Trait Implementations

impl Aggregator for SumAggregator

fn update(&self, number: &Number, descriptor: &Descriptor) -> Result<()>

Update receives a new measured value and incorporates it into the aggregation. Update calls may be called concurrently.

fn synchronized_move(
    &self,
    other: &Arc<dyn Aggregator + Send + Sync>,
    descriptor: &Descriptor
) -> Result<()>

This method is called during collection to finish one period of aggregation by atomically saving the currently-updating state into the argument Aggregator.

fn merge(
    &self,
    other: &(dyn Aggregator + Send + Sync),
    descriptor: &Descriptor
) -> Result<()>

This combines the checkpointed state from the argument Aggregator into this Aggregator. merge is not synchronized with respect to update or synchronized_move.

fn as_any(&self) -> &dyn Any

Returns the implementing aggregator as Any for downcasting.

impl Debug for SumAggregator

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

Formats the value using the given formatter.

impl Default for SumAggregator

fn default() -> SumAggregator

Returns the “default value” for a type.

impl Subtractor for SumAggregator

fn subtract(
    &self,
    operand: &(dyn Aggregator + Send + Sync),
    result: &(dyn Aggregator + Send + Sync),
    descriptor: &Descriptor
) -> Result<()>

Subtract subtracts the operand from this Aggregator and outputs the value in result.

impl Sum for SumAggregator

fn sum(&self) -> Result<Number>

The sum of the currently aggregated metrics
