Enum polars_core::error::ArrowError

#[non_exhaustive]
pub enum ArrowError {
    NotYetImplemented(String),
    External(String, Box<dyn Error + Send + Sync + 'static, Global>),
    Io(Error),
    InvalidArgumentError(String),
    ExternalFormat(String),
    Overflow,
    OutOfSpec(String),
}

Enum with all errors in this crate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotYetImplemented(String)

Returned when functionality is not yet available.

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

Wrapper for an error triggered by a dependency

Io(Error)

Wrapper for IO errors

InvalidArgumentError(String)

When an invalid argument is passed to a function.

ExternalFormat(String)

Error during import or export to/from a format

Overflow

Whenever pushing to a container fails because it does not support more entries. The solution is usually to use a higher-capacity container-backing type.

OutOfSpec(String)

Whenever incoming data from the C data interface, IPC or Flight does not fulfil the Arrow specification.

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
