Struct ChaosConfig 

pub struct ChaosConfig { /* private fields */ }

Configuration controlling how a ChaosEventStore injects failures.

A ChaosConfig holds an optional deterministic seed plus the probabilities of injecting store failures and version conflicts. The probabilities default to 0.0 (no injection); use the builder methods to raise them.

Start from either ChaosConfig::default (random seed, no injection) or ChaosConfig::deterministic (fixed seed for reproducible runs), then chain with_failure_probability and with_version_conflict_probability.

use eventcore_testing::chaos::ChaosConfig;

let config = ChaosConfig::deterministic()
    .with_failure_probability(0.25)
    .with_version_conflict_probability(0.1);

Implementations

impl ChaosConfig

pub fn deterministic() -> Self

Creates a config with a fixed seed so injected failures are reproducible.

The failure and version-conflict probabilities still default to 0.0; chain with_failure_probability and with_version_conflict_probability to enable injection.

pub fn with_failure_probability(self, probability: f32) -> Self

Sets the probability of injecting a store failure on reads and appends.

probability is clamped to the [0.0, 1.0] range, where 0.0 never injects a failure and 1.0 always does.

pub fn with_version_conflict_probability(self, probability: f32) -> Self

Sets the probability of injecting a version conflict on appends.

probability is clamped to the [0.0, 1.0] range, where 0.0 never injects a conflict and 1.0 always does.
