Struct PoolConfig 

pub struct PoolConfig {
    pub size: usize,
    pub reconnect_backoff: Duration,
    pub circuit_open_duration: Duration,
    pub exhaustion_policy: ExhaustionPolicy,
    pub validation_mode: ValidationMode,
    pub circuit_failure_threshold: u32,
    pub shutdown_timeout: Duration,
}

Pool configuration.

Fields

size: usize

Number of connections in the pool

reconnect_backoff: Duration

Backoff duration before retry reconnection

circuit_open_duration: Duration

How long circuit breaker stays open

exhaustion_policy: ExhaustionPolicy

What to do when pool is exhausted

validation_mode: ValidationMode

How to handle startup failures

circuit_failure_threshold: u32

Number of consecutive failures before opening circuit

shutdown_timeout: Duration

Timeout for graceful shutdown drain.

Note: This field is currently reserved for future use. The current shutdown implementation closes connections immediately.
