Enum UdfError 

#[non_exhaustive]
pub enum UdfError {
    Registration(String),
    DataFusion(DataFusionError),
    RemoteDisabled,
    Manifest(ManifestError),
    Transport(TransportError),
}

Errors surfaced by the crate’s registration entry points.

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.

Registration(String)

A UDF could not be registered on the session context.

DataFusion(DataFusionError)

An error propagated from DataFusion.

RemoteDisabled

A manifest_path was supplied but the remote feature is not enabled.

Manifest(ManifestError)

The remote manifest was invalid.

Transport(TransportError)

A remote service could not be connected at startup.

Trait Implementations

impl Debug for UdfError

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

Formats the value using the given formatter.

impl Display for UdfError

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

Formats the value using the given formatter.

impl Error for UdfError

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.
