Enum ErrorCategory 

pub enum ErrorCategory {
    Io,
    UnknownFormat,
    Parse,
    Data,
    Output,
}

Coarse classification of an Error, for callers that map onto their own taxonomy (the Python layer’s exception subclasses, C ABI status codes, a CLI exit code). Distinguishing “the input file is bad” from “the operation can’t run on this otherwise-valid case” is the split callers actually branch on, and it’s a property of the error, not of the binding that surfaces it.

Deliberately not #[non_exhaustive] (unlike Error): a category-mapping match should fail to compile when a category is added, so every binding is forced to decide how to surface it.

Variants

Io

Underlying I/O failure reading or writing a file.

UnknownFormat

The requested format is unknown or can’t be inferred from the path.

Parse

The input is malformed or unparseable.

Data

A well-formed case can’t satisfy the requested operation.

Output

An output serialization step (matrix-market, Parquet) failed.

Trait Implementations

impl Clone for ErrorCategory

fn clone(&self) -> ErrorCategory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCategory

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

Formats the value using the given formatter.

impl PartialEq for ErrorCategory

fn eq(&self, other: &ErrorCategory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
