lib.rs
:
A thread-safe, Future
-aware metrics library.
Many programs need to information about runtime performance: the number of requests
served, a distribution of request latency, the number of failures, the number of loop
iterations, etc. tacho::new
creates a shareable, scopable metrics registry and a
Reporter
. The Scope
supports the creation of Counter
, Gauge
, and Stat
handles that may be used to report values. Each of these receivers maintains a weak
reference back to the central stats registry.
Performance
Labels are stored in a BTreeMap
because they are used as hash keys and, therefore,
need to implement Hash
.
