Struct PoolConnectionMetadata 

#[non_exhaustive]
pub struct PoolConnectionMetadata {
    pub age: Duration,
    pub idle_for: Duration,
}

Metadata for the connection being processed by a PoolOptions callback.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

age: Duration

The duration since the connection was first opened.

For after_connect, this is Duration::ZERO.

idle_for: Duration

The duration that the connection spent in the idle queue.

Only relevant for before_acquire. For other callbacks, this is Duration::ZERO.
