Enum rocket_contrib::databases::DbError[−][src]

pub enum DbError<T> {
    Custom(T),
    PoolError(Error),
}
Expand description

A wrapper around r2d2::Errors or a custom database error type.

This type is only relevant to implementors of the Poolable trait. See the Poolable documentation for more information on how to use this type.

Variants

Custom(T)

The custom error type to wrap alongside r2d2::Error.

PoolError(Error)

The error returned by an r2d2 pool.
