Enum CloseReason 

pub enum CloseReason {
    Expired,
    MaxUses,
    Idle,
    Unhealthy,
    Error,
    ResetFailed,
    Discarded,
    PoolClosed,
}

Why a connection left the pool. The string values (CloseReason::as_str) are wire values kept identical across every poolyglot language — do not localize them.

Variants

Expired

max_lifetime reached (rotation).

MaxUses

max_uses reached (rotation).

Idle

Sat idle longer than max_idle_time.

Unhealthy

Failed validation.

Error

The caller’s work raised and the connection is suspect.

ResetFailed

reset() failed on release.

Discarded

The caller asked for it to be discarded.

PoolClosed

The pool was closed.
