Struct CircuitBreakerConfig 

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

Circuit breaker configuration.

Example

use ccxt_core::circuit_breaker::CircuitBreakerConfig;
use std::time::Duration;

let config = CircuitBreakerConfig {
    failure_threshold: 5,
    reset_timeout: Duration::from_secs(30),
    success_threshold: 1,
};

Fields

failure_threshold: u32

Number of consecutive failures before opening the circuit.

When the failure count reaches this threshold, the circuit transitions from Closed to Open state.

Default: 5

reset_timeout: Duration

Time to wait in Open state before transitioning to HalfOpen.

After this duration elapses, the circuit breaker will allow a test request to check if the service has recovered.

Default: 30 seconds

success_threshold: u32

Number of consecutive successes needed to close the circuit from HalfOpen.

When in HalfOpen state, this many successful requests are required before transitioning back to Closed state.

Default: 1

Implementations

impl CircuitBreakerConfig

pub fn new( failure_threshold: u32, reset_timeout: Duration, success_threshold: u32, ) -> CircuitBreakerConfig

Creates a new circuit breaker configuration with the given parameters.

Arguments

• failure_threshold - Number of failures before opening the circuit
• reset_timeout - Time to wait before testing recovery
• success_threshold - Number of successes needed to close the circuit

pub fn validate(&self) -> Result<ValidationResult, ConfigValidationError>

Validates the circuit breaker configuration.

Returns

Returns Ok(ValidationResult) if the configuration is valid. Returns Err(ConfigValidationError) if the configuration is invalid.

Validation Rules

• failure_threshold must be > 0
• success_threshold must be > 0
• reset_timeout must be >= 1 second

Example

use ccxt_core::circuit_breaker::CircuitBreakerConfig;

let config = CircuitBreakerConfig::default();
assert!(config.validate().is_ok());
