Enum diesel::result::Error

pub enum Error {
    InvalidCString(NulError),
    DatabaseError(DatabaseErrorKind, Box<DatabaseErrorInformation + Send + Sync>),
    NotFound,
    QueryBuilderError(Box<StdError + Send + Sync>),
    DeserializationError(Box<StdError + Send + Sync>),
    SerializationError(Box<StdError + Send + Sync>),
    RollbackTransaction,
    // some variants omitted
}

The generic "things can fail in a myriad of ways" enum. This type is not intended to be exhaustively matched, and new variants may be added in the future without a major version bump.

Variants

InvalidCString(NulError)DatabaseError(DatabaseErrorKind, Box<DatabaseErrorInformation + Send + Sync>)NotFoundQueryBuilderError(Box<StdError + Send + Sync>)DeserializationError(Box<StdError + Send + Sync>)SerializationError(Box<StdError + Send + Sync>)RollbackTransaction

You can return this variant inside of a transaction when you want to roll it back, but have no actual error to return. Diesel will never return this variant unless you gave it to us, and it can be safely ignored in error handling.
