Enum AppError

pub enum AppError {
    DateTimeError(DateTimeError),
    SerializationError(Error),
    GeneralError(Error),
    Other(String),
    SimulatedError,
    EnvVarError(VarError),
}

Custom error type for the application.

This error type encapsulates all possible errors that might occur in the application, including simulated errors for testing and environment variable retrieval errors.

Variants

DateTimeError(DateTimeError)

Error that occurs during datetime operations.

SerializationError(Error)

Error that occurs during serialization.

GeneralError(Error)

General I/O or parsing error.

Other(String)

Error that occurs during other operations.

SimulatedError

Error for simulating a failure in test mode.

EnvVarError(VarError)

Error that occurs when retrieving environment variables.

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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.
