[−][src]Struct metered::InFlight
A metric providing an in-flight gauge, showing how many calls are currently active for an expression.
This is a light-weight metric.
This makes sense mostly in a multi-threaded situation where several threads may call the same method constantly, and we want to monitor how many are active at a given time.
The Throughput
metric shows an alternative view of the same picture, by reporting how many transactions per seconds are processed by an expression.
By default, InFlight
uses a lock-free u64
Gauge
, which makes sense in multithread scenarios. Non-threaded applications can gain performance by using a std::cell:Cell<u64>
instead.
