Implementations§
Source§impl LatencyDistribution
impl LatencyDistribution
Sourcepub fn fit(
workload: &WorkloadConfig,
model: DistributionModel,
) -> Result<Self, PoolsimError>
pub fn fit( workload: &WorkloadConfig, model: DistributionModel, ) -> Result<Self, PoolsimError>
Fits a latency distribution for a workload and selected model.
If workload.raw_samples_ms is present, empirical fitting is used regardless
of model.
§Errors
Returns PoolsimError::Distribution when distribution parameters cannot
be derived.
Sourcepub fn sample_ms<R: Rng + ?Sized>(&self, rng: &mut R) -> f64
pub fn sample_ms<R: Rng + ?Sized>(&self, rng: &mut R) -> f64
Draws one latency sample in milliseconds.
Sourcepub fn percentile_ms(&self, p: f64) -> Result<f64, PoolsimError>
pub fn percentile_ms(&self, p: f64) -> Result<f64, PoolsimError>
Returns the requested percentile in milliseconds.
p is clamped into [0, 1].
§Errors
Returns PoolsimError::Distribution when percentile evaluation fails for
the current parameterization.
