Module fault 

Fault injection for resilience testing.

Provides configurable fault injection to test error handling and system resilience under failure conditions.

Example

use fastapi_core::fault::{FaultConfig, FaultInjector, FaultType};

let config = FaultConfig::new()
    .add(FaultType::Delay { ms: 100 }, 0.1)     // 10% chance of 100ms delay
    .add(FaultType::Error { status: 500 }, 0.05); // 5% chance of 500 error

let injector = FaultInjector::new(config);
let fault = injector.check(42); // deterministic based on request ID

Structs

FaultConfig

Configuration for fault injection.

FaultInjector

Deterministic fault injector for testing.

FaultRule

A single fault rule: a fault type and the probability of it firing (0.0–1.0).

Enums

FaultType

Types of faults that can be injected.
