Enum LatencyDistribution 

pub enum LatencyDistribution {
    Uniform,
    Bimodal,
}

Latency distribution mode for network operations.

Controls how latencies are sampled for network operations. FDB ref: sim2.actor.cpp:317-329 (halfLatency())

Real-World Scenario

Real networks exhibit bimodal latency patterns where most operations are fast, but a small percentage experience significantly higher latency (tail latency). This is crucial for testing:

• P99/P99.9 latency handling
• Timeout tuning
• Retry logic under tail latency conditions

Variants

Uniform

Uniform distribution within the configured range. All latencies equally likely within [min, max].

Bimodal

Bimodal distribution matching FDB’s halfLatency() pattern.

• 99.9% of operations: fast latency (within configured range)
• 0.1% of operations: slow latency (multiplied by slow_latency_multiplier)

Trait Implementations

impl Clone for LatencyDistribution

fn clone(&self) -> LatencyDistribution

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LatencyDistribution

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LatencyDistribution

fn default() -> LatencyDistribution

Returns the “default value” for a type.

impl PartialEq for LatencyDistribution

fn eq(&self, other: &LatencyDistribution) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
