Enum ManagerError 

#[non_exhaustive]
pub enum ManagerError {
    Connection {
        db_file: String,
        backtrace: ConnectionError,
    },
    Join(JoinError),
    Query(Error),
}

Error returned while creating a connection

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.

Connection

Fields

db_file: String

Connection to the database file

backtrace: ConnectionError

Underling connection error

Join(JoinError)
