Struct opentelemetry::sdk::metrics::aggregators::MinMaxSumCountAggregator

pub struct MinMaxSumCountAggregator { /* fields omitted */ }

This is supported on crate feature metrics only.

An Aggregator that aggregates events that form a distribution, keeping only the min, max, sum, and count.

Trait Implementations

impl Aggregator for MinMaxSumCountAggregator

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,
    aggregator: &(dyn Aggregator + Send + Sync),
    desc: &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 Count for MinMaxSumCountAggregator

fn count(&self) -> Result<u64>

The count of the currently aggregated metrics

impl Debug for MinMaxSumCountAggregator

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

Formats the value using the given formatter.

impl Max for MinMaxSumCountAggregator

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

The max of the currently aggregated metrics

impl Min for MinMaxSumCountAggregator

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

The min of the currently aggregated metrics

impl Sum for MinMaxSumCountAggregator

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

The sum of the currently aggregated metrics
