Enum PyPluginError 

#[non_exhaustive]
pub enum PyPluginError {
    SignatureUnrecognized(String),
    PythonException {
        qname: String,
        message: String,
        traceback: String,
    },
    ManifestInvalid(String),
    RegistrarRejected(String),
    ArrowConversion(String),
    Internal(String),
}

Errors specific to the PyO3 loader.

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.

SignatureUnrecognized(String)

The Python callable’s signature was not recognized (unknown type name in args / returns, or the callable could not be resolved by name in the module namespace).

PythonException

A Python Exception was raised inside a plugin callable. traceback carries the formatted Python traceback string.

Fields

qname: String

Qualified plugin function name.

message: String

repr(e) of the Python exception.

traceback: String

Formatted Python traceback (best effort).

ManifestInvalid(String)

The plugin’s declared manifest did not pass validation (missing required field, unknown type name, duplicate qname).

RegistrarRejected(String)

The host’s PluginRegistrar rejected one of our adapters (capability missing, qname namespace violation, duplicate).

ArrowConversion(String)

Conversion between an Arrow array and a PyArrow object (via the PyCapsule C Data Interface) failed: unsupported type, capsule shape mismatch, or null pointer.

Internal(String)

Internal / unexpected error.

Trait Implementations

impl Debug for PyPluginError

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

Formats the value using the given formatter.

impl Display for PyPluginError

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

Formats the value using the given formatter.

impl Error for PyPluginError

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<PluginError> for PyPluginError

fn from(err: PluginError) -> Self

Converts to this type from the input type.
