Struct CircuitBreakerConfig 

pub struct CircuitBreakerConfig {
    pub failure_threshold: u32,
    pub success_threshold: u32,
    pub open_duration: Duration,
}

Configuration for the circuit breaker pattern.

The circuit breaker monitors failures and temporarily stops sending requests to a failing service, giving it time to recover.

States

• Closed — Normal operation. Failures are counted; when failure_threshold consecutive failures occur, the circuit opens.
• Open — All calls are rejected with CamelError::CircuitOpen. After open_duration elapses, the circuit transitions to half-open.
• Half-Open — A single probe call is allowed through. If it succeeds (success_threshold times), the circuit closes. If it fails, the circuit reopens.

Fields

failure_threshold: u32

Number of consecutive failures before opening the circuit.

success_threshold: u32

Number of successful probes in half-open state before closing.

Current limitation: Only 1 is effectively supported. The state machine resets to Closed on the first successful half-open probe regardless of this value. Multi-probe half-open tracking is deferred.

open_duration: Duration

How long the circuit stays open before allowing a probe.
