}

Configuration for a generic resource pool.

Fields

min_size: usize

Minimum resources to keep in pool.

max_size: usize

Maximum resources in pool.

acquire_timeout: Duration

Timeout for acquire operations.

idle_timeout: Duration

Maximum time a resource can be idle before eviction.

max_lifetime: Duration

Maximum lifetime of a resource.

health_check_on_acquire: bool

Perform health check before returning idle resources.

health_check_interval: Option<Duration>

Periodic health check interval for idle resources. If None, periodic health checks are disabled.

evict_unhealthy: bool

Remove unhealthy resources immediately when detected.

warmup_connections: usize

Pre-create this many connections on pool init.

warmup_timeout: Duration

Timeout for warmup phase.

warmup_failure_strategy: WarmupStrategy

Strategy when warmup partially fails.
