Struct FallbackPoolConfig 

pub struct FallbackPoolConfig {
    pub max_idle: usize,
    pub max_age_secs: u64,
    pub fill_batch: usize,
    pub fill_delay_ms: u64,
}

Configuration for fallback connection warm pool.

Warm pool semantics:

• Pre-connects up to max_idle fresh connections in the background.
• Connections are handed out once and NOT returned to the pool.
• Pool is periodically refilled.

Fields

max_idle: usize

Maximum idle connections to keep in pool.

max_age_secs: u64

Maximum age of pooled connections in seconds.

fill_batch: usize

Warm-fill batch size per cycle (1..=max_idle).

fill_delay_ms: u64

Delay (ms) between each connection attempt within a batch.
