Variants

NotYetImplemented(String)

Returned when functionality is not yet available.

Tuple Fields of NotYetImplemented

0: String

External(String, Box<dyn Error + Send + Sync + 'static, Global>)

Triggered by an external error, such as CSV, serde, chrono.

Tuple Fields of External

0: String1: Box<dyn Error + Send + Sync + 'static, Global>

Schema(String)

Implementations

impl ArrowError

pub fn from_external_error(
    error: impl Error + Send + Sync + 'static
) -> ArrowError

Wraps an external error in an ArrowError.

Trait Implementations

impl Debug for ArrowError

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

Formats the value using the given formatter.

impl Display for ArrowError

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

Formats the value using the given formatter.

impl Error for ArrowError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
