Struct metered::Throughput

pub struct Throughput<T: Instant = StdInstant, P: RecordThroughput = AtomicTxPerSec<T>>(_, _);

A metric providing a transaction per second count backed by an histogram.

Because it retrieves the current time before calling the expression, stores it to appropriatly build time windows of 1 second and registers results to an histogram, this is a rather heavy-weight metric better applied at entry-points.

By default, Throughput uses an atomic transaction count backend and a synchronized time source, which work better in multithread scenarios. Non-threaded applications can gain performance by using unsynchronized structures instead.
