Enum Error 

pub enum Error {
    InvalidUrl(String),
    PoolClosed,
    PoolExhausted,
    PoolTimedOut,
    Unsupported(String),
}

Errors returned by the facade.

Driver errors are kept intact so callers can still inspect or display the original mariadb, mysql, postgres, or sqlite failure.

Variants

InvalidUrl(String)

A database URL could not be parsed or used.

PoolClosed

The pool was closed and no longer hands out connections.

PoolExhausted

The pool is at capacity and cannot hand out another connection without waiting.

PoolTimedOut

Waiting for a pool connection hit the configured timeout.

Unsupported(String)

The requested conversion or operation is not supported by the facade.
