Enum RlineError 

pub enum RlineError {
    ConfigurationError(String),
    RuntimeError(String),
    TooManyFailsError(usize),
    BadTypeError(String),
}

Represents any error that may occur during rline initialization and running.

Variants

ConfigurationError(String)

This exception is probably the most crucial rline error. It is thrown whenever a required property is missing, or if a mismatch in your configuration like invalid dag. You may have a typo somewhere.

RuntimeError(String)

A RuntimeError is raised whenever a connector encounters an error. Typically an I/O or connection error. It is of highest importance to raise a useful error message to the user, and to keep the error trace when available.

TooManyFailsError(usize)

A TooManyFailsError thrown whenever the exit condition of number of failing rows is reached.

BadTypeError(String)

A RuntimeError is raised whenever you try to cast a Value to a bad type.

Implementations

impl RlineError

pub fn runtime_error(cause: &dyn Error) -> Self

Returns a new RuntimeError keeping the trace of the causing error.

pub fn configuration_error(cause: &dyn Error) -> Self

Returns a new ConfigurationError keeping the trace of the causing error.

Trait Implementations

impl Clone for RlineError

fn clone(&self) -> RlineError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RlineError

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

Formats the value using the given formatter.

impl Display for RlineError

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

Formats the value using the given formatter.

impl Error for RlineError

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.
