An aggregator which stores metrics in an array.

Trait Implementations

impl Aggregator for ArrayAggregator

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), 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 ArrayAggregator

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

The count of the currently aggregated metrics

impl Debug for ArrayAggregator

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

Formats the value using the given formatter.

impl Default for ArrayAggregator

fn default() -> ArrayAggregator

Returns the “default value” for a type.

impl Points for ArrayAggregator

fn points(&self) -> Result<Vec<Number>>

The raw set of points currently aggregated
