Enum reool::CheckoutMode

pub enum CheckoutMode {
    Immediately,
    Wait,
    PoolDefault,
    Until(Instant),
}

Various options on retrieving a connection

From implementations

• Duration: Until
• Instant: Until

Variants

Immediately

Expect a connection to be returned immediately. If there is none available return an error immediately. In that case a CheckoutErrorKind::NoConnection will be returned

This mode will always try to get a connection

Wait

Wait until there is a connection

PoolDefault

Use the default configured for the pool

Until(Instant)

Checkout before the given Instant is elapsed. If the given timeout is elapsed, no attempt to checkout a connection will be made. In that case a CheckoutErrorKind::CheckoutTimeout will be returned.
