[][src]Enum diesel::result::ConnectionError

#[non_exhaustive]pub enum ConnectionError {
    InvalidCString(NulError),
    BadConnection(String),
    InvalidConnectionUrl(String),
    CouldntSetupConfiguration(Error),
}

Errors which can occur during Connection::establish

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
InvalidCString(NulError)

The connection URL contained a NUL byte.

BadConnection(String)

The database returned an error.

InvalidConnectionUrl(String)

The connection URL could not be parsed.

CouldntSetupConfiguration(Error)

Diesel could not configure the database connection.

Diesel may try to automatically set session specific configuration values, such as UTF8 encoding, or enabling the || operator on MySQL. This variant is returned if an error occurred executing the query to set those options. Diesel will never affect global configuration.
