Enum Fault 

pub enum Fault {
    ConnectionLost,
}

A fault that can be injected into the next operation routed through the driver. Faults are consumed in FIFO order: each exec call pops at most one fault off the queue before delegating (or short-circuiting past) the underlying driver.

Variants

ConnectionLost

Causes the next exec to return Error::connection_lost without touching the underlying connection. The wrapping InstrumentedConnection’s is_valid flips to false, mirroring what a real connection-lost error would do and prompting the pool to evict the connection.
