[−][src]Enum diesel::result::ConnectionError
Errors which can occur during Connection::establish
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.
