Struct PullController

pub struct PullController { /* private fields */ }

Available on crate feature metrics only.

Pull controllers are typically used in an environment where there are multiple readers. It is common, therefore, when configuring a BasicProcessor for use with this controller, to use a ExportKind::Cumulative strategy and the with_memory(true) builder option, which ensures that every CheckpointSet includes full state.

Implementations

impl PullController

pub fn provider(&self) -> RegistryMeterProvider

The provider for this controller

pub fn collect(&mut self) -> Result<()>

Collects all metrics if the last collected at time is past the current period

Trait Implementations

impl CheckpointSet for PullController

fn try_for_each( &mut self, export_selector: &dyn ExportKindFor, f: &mut dyn FnMut(&Record<'_>) -> Result<()>, ) -> Result<()>

This iterates over aggregated checkpoints for all metrics that were updated during the last collection period. Each aggregated checkpoint returned by the function parameter may return an error.

impl Debug for PullController

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

Formats the value using the given formatter.
