Crate influxive_otel_atomic_obs 

Opentelemetry observable metric implementations based on std::sync::atomic types. Opentelemetry has a concept of “observable” metrics that are not reported as they are updated, but rather, when an update happens, they are polled. For ease-of-use in code, it is often desirable to have these metrics be backed by std::sync::atomic types, so that they can be easily updated throughout the code, and fetched whenever a metric reporting poll occurs. This crate provides the MeterExt trait and associated types to make it easy to use std::sync::atomic backed metrics with opentelemetry.

Example

use influxive_otel_atomic_obs::MeterExt;

let (my_metric, _) = opentelemetry_api::global::meter("my_meter")
    .u64_observable_gauge_atomic("my_metric", 0)
    .init();

my_metric.set(66); // probably will not be reported
my_metric.set(99); // probably will not be reported
my_metric.set(42); // will be reported next time reporting runs
