Circuit breaker configuration

Fields

failure_threshold: u32

Number of failures to trigger circuit open

failure_window: Duration

Time window for counting failures

open_timeout: Duration

How long to keep circuit open before trying half-open

success_threshold: u32

Number of successful requests to close from half-open

Implementations

impl CircuitBreakerConfig

pub fn from_env() -> CircuitBreakerConfig

Create config from environment variables with sensible defaults.

Environment variables:

• CIRCUIT_FAILURE_THRESHOLD: Number of failures to trigger open (default: 5)
• CIRCUIT_FAILURE_WINDOW_SECS: Time window for counting failures (default: 5)
• CIRCUIT_OPEN_TIMEOUT_SECS: How long circuit stays open (default: 5)
• CIRCUIT_SUCCESS_THRESHOLD: Successes needed to close from half-open (default: 2)

Lab environments (single machine): Use defaults or lower values (1-5s) Production environments: Consider higher values (10-30s) for network variability
