Enum ExtensionLoweringError 

pub enum ExtensionLoweringError {
    Message {
        message: String,
        kind: ErrorKind,
    },
    Source {
        kind: ErrorKind,
        source: Box<dyn StdError + Send + Sync + 'static>,
    },
}

Error returned when an extension cannot expand itself into standard ops.

Examples

use tenferro_ops::ext_op::ExtensionLoweringError;

let err = ExtensionLoweringError::new("example extension cannot lower");
assert!(err.to_string().contains("cannot lower"));

Variants

Message

A lowering failure that has no typed source.

Fields

message: String

Human-readable lowering detail.

kind: ErrorKind

Coarse classification supplied by the extension owner.

Source

A lowering failure retaining the domain source that caused it.

Fields

kind: ErrorKind

Coarse classification supplied by the extension owner.

source: Box<dyn StdError + Send + Sync + 'static>

Original typed lowering source.

Implementations

impl ExtensionLoweringError

pub fn new(message: impl Into<String>) -> Self

Create a lowering error with a human-readable diagnostic.

Examples

use tenferro_ops::ext_op::ExtensionLoweringError;

let err = ExtensionLoweringError::new("shape must be static");
assert_eq!(err.to_string(), "shape must be static");

pub fn new_with_kind(kind: ErrorKind, message: impl Into<String>) -> Self

Create a lowering error with an explicit coarse classification.

Examples

use tenferro_ops::ext_op::ExtensionLoweringError;
use tenferro_tensor::ErrorKind;

let err = ExtensionLoweringError::new_with_kind(
    ErrorKind::Unsupported,
    "extension is not supported by this lowering target",
);
assert_eq!(err.kind(), ErrorKind::Unsupported);

pub fn from_source<E>(source: E) -> Self

where E: StdError + Send + Sync + 'static,

Create a lowering error while retaining a typed source.

Examples

use std::error::Error as _;
use tenferro_ops::ext_op::ExtensionLoweringError;

let source = std::io::Error::new(std::io::ErrorKind::Other, "shape unavailable");
let err = ExtensionLoweringError::from_source(source);
assert!(err.source().is_some());

pub fn from_source_with_kind<E>(kind: ErrorKind, source: E) -> Self

where E: StdError + Send + Sync + 'static,

Create a lowering error with a typed source and explicit classification.

Examples

use tenferro_ops::ext_op::ExtensionLoweringError;
use tenferro_tensor::ErrorKind;

let err = ExtensionLoweringError::from_source_with_kind(
    ErrorKind::BackendFailure,
    std::io::Error::other("backend rejected lowering"),
);
assert_eq!(err.kind(), ErrorKind::BackendFailure);
assert!(std::error::Error::source(&err).is_some());

pub fn kind(&self) -> ErrorKind

Return the stable classification carried by this lowering failure.

Examples

use tenferro_ops::ext_op::ExtensionLoweringError;
use tenferro_tensor::ErrorKind;

let error = ExtensionLoweringError::new_with_kind(
    ErrorKind::Unsupported,
    "target has no lowering",
);
assert_eq!(error.kind(), ErrorKind::Unsupported);

Trait Implementations

impl Debug for ExtensionLoweringError

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

Formats the value using the given formatter.

impl Display for ExtensionLoweringError

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

Formats the value using the given formatter.

impl Error for ExtensionLoweringError

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
