Struct usl::Measurement [−][src]
Expand description
A simultaneous measurement of at least two of the parameters of Little’s Law: concurrency, throughput, and latency. The third parameter is inferred from the other two.
Measurement instances can be created from pairs of dimensional types: u32
for the number of
concurrent events, f64
for the average rate of events, and Duration
for the average duration
of events:
use usl::Measurement; use std::time::Duration; let m: Measurement = (30, 1000.0).into(); let m: Measurement = (1000.0, 30).into(); let m: Measurement = (30, Duration::from_millis(200)).into(); let m: Measurement = (Duration::from_millis(200), 30).into(); let m: Measurement = (1000.0, Duration::from_millis(200)).into(); let m: Measurement = (Duration::from_millis(200), 1000.0).into();
Fields
n: f64
The average number of concurrent events.
x: f64
The long-term arrival rate of events, in events/sec.
r: f64
The average duration of events, in seconds.

[src]
impl Measurement
[src]pub fn concurrency_and_latency(n: u32, r: Duration) -> Measurement
[src]
pub fn concurrency_and_latency(n: u32, r: Duration) -> Measurement
[src]Create a measurement of a system’s latency at a given level of concurrency. The throughput of the system is derived via Little’s Law.
pub fn concurrency_and_throughput(n: u32, x: f64) -> Measurement
[src]
pub fn concurrency_and_throughput(n: u32, x: f64) -> Measurement
[src]Create a measurement of a system’s throughput at a given level of concurrency. The latency of the system is derived via Little’s Law.
pub fn throughput_and_latency(x: f64, r: Duration) -> Measurement
[src]
pub fn throughput_and_latency(x: f64, r: Duration) -> Measurement
[src]Create a measurement of a system’s latency at a given level of throughput. The concurrency of the system is derived via Little’s Law.
