Enum Error 

pub enum Error {
    ConnectionPool(Error),
    Deserialization(Error),
    Migration(Error),
    Sql(Error),
    InsertionFailure,
    InconsistentConfig,
    Failure(String),
}

Database operations generate errors for multiple reasons, this is a unified error type that our functions can return.

Variants

ConnectionPool(Error)

Error from the connection pool

Deserialization(Error)

Error in JSON serialization or deserialization

Migration(Error)

Error during database migrations

Sql(Error)

Error from SQLite operations

InsertionFailure

Failure to insert data

InconsistentConfig

Conflicting configuration detected

Failure(String)

Generic failure with message

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
