Enum Error 

pub enum Error {
    ShapeMismatch {
        expected: Vec<usize>,
        got: Vec<usize>,
    },
    InvalidArgument(String),
}

Errors produced while parsing, planning, or lowering einsum expressions.

Examples

use tenferro_einsum::Error;

let err = Error::ShapeMismatch {
    expected: vec![2, 3],
    got: vec![2, 4],
};
assert!(err.to_string().contains("shape mismatch"));

Variants

ShapeMismatch

Tensor shapes are incompatible for an einsum expression.

Fields

expected: Vec<usize>

Expected shape or dimension sizes.

got: Vec<usize>

Actual shape or dimension sizes.

InvalidArgument(String)

An invalid einsum argument was provided.

Implementations

impl Error

pub fn to_tensor_error(&self, op: &'static str) -> Error

Convert this einsum error into a tensor backend failure.

Examples

use tenferro_einsum::Error;
use tenferro_tensor::Error as TensorError;

let err = Error::InvalidArgument("bad subscripts".into())
    .to_tensor_error("einsum_extension");

assert!(matches!(
    err,
    TensorError::BackendFailure {
        op: "einsum_extension",
        ..
    }
));

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Error) -> 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.
