Enum TransferredError 

pub enum TransferredError {
    Source(String),
    EmptySource,
    Destination(String),
    Io(Error),
    Arrow(ArrowError),
    Other(String),
}

Root error type. Every fallible operation in transferred returns Result<T, TransferredError>. Maps to Python transferred.TransferredError at the FFI boundary.

Variants

Source(String)

A source connector failed to read or produce data.

EmptySource

Source produced zero batches (Python EmptySourceError).

Destination(String)

A destination connector failed to write or finalize output.

Io(Error)

Underlying I/O failure (filesystem, network).

Arrow(ArrowError)

Arrow compute or schema error surfaced from the data layer.

Other(String)

Any error that does not fit the other variants.

Implementations

impl TransferredError

pub fn source<S: Into<String>>(msg: S) -> Self

Construct a TransferredError::Source from any message.

pub fn destination<S: Into<String>>(msg: S) -> Self

Construct a TransferredError::Destination from any message.

pub fn other<S: Into<String>>(msg: S) -> Self

Construct a TransferredError::Other from any message.

Trait Implementations

impl Debug for TransferredError

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

Formats the value using the given formatter.

impl Display for TransferredError

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

Formats the value using the given formatter.

impl Error for TransferredError

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.

impl From<ArrowError> for TransferredError

impl From<Error> for TransferredError

fn from(source: Error) -> Self
