Enum StorageError 

pub enum StorageError {
    ScalarKindMismatch {
        expected: &'static str,
        actual: &'static str,
        operation: &'static str,
    },
    LengthMismatch {
        operation: &'static str,
        left: usize,
        right: usize,
    },
    InvalidStructuredStorage(String),
    OperationNotSupported {
        operation: &'static str,
        left: &'static str,
        right: &'static str,
    },
    RealScalarRequired {
        operation: &'static str,
        a: String,
        b: String,
    },
}

Errors returned by storage payload and elementwise operations.

Use this to distinguish scalar-kind mismatches, length mismatches, and invalid structured-storage metadata from general backend failures.

Examples

use tensor4all_tensorbackend::{Storage, StorageError};

let storage = Storage::from_dense_col_major(vec![1.0_f64], &[1]).unwrap();
let err = storage.payload_c64_col_major_vec().unwrap_err();
assert!(matches!(err, StorageError::ScalarKindMismatch { .. }));

Variants

ScalarKindMismatch

The storage scalar kind did not match the requested operation.

Fields

expected: &'static str

The scalar kind that the caller requested.

actual: &'static str

The scalar kind actually stored.

operation: &'static str

Human-readable operation description.

LengthMismatch

Two storages had different payload lengths for an elementwise operation.

Fields

operation: &'static str

Name of the operation being performed.

left: usize

Left-hand payload length.

right: usize

Right-hand payload length.

InvalidStructuredStorage(String)

Structured storage metadata was invalid after an operation.

OperationNotSupported

The requested operation does not support the provided storage kinds.

Fields

operation: &'static str

Name of the operation being performed.

left: &'static str

Left-hand storage kind.

right: &'static str

Right-hand storage kind.

RealScalarRequired

The requested operation requires real scalars but at least one scalar was complex.

Fields

operation: &'static str

Name of the operation being performed.

a: String

Left scalar display string.

b: String

Right scalar display string.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
