Connection pool configuration.

Construct via ConnPoolConfig::default and update only the fields you care about. Marked #[non_exhaustive] so adding new tuning knobs in future minor releases is not a breaking change.

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.

addr: String

Address (host:port).

user: String

User.

password: String

Password.

database: String

Database.

min_idle: usize

Minimum idle connections to maintain.

max_size: usize

Maximum total connections.

max_lifetime: Duration

Maximum lifetime per connection (with jitter applied).

max_lifetime_jitter: Duration

Jitter range for max_lifetime (± this value).

checkout_timeout: Duration

Timeout waiting for a connection from the pool.

maintenance_interval: Duration

How often to run the maintenance task.

test_on_checkout: bool

Whether to verify connections on checkout.
