    Backend(Error),

        message: String,
    },

    UnsupportedStructuredLinalg {

}

Shared error type for dynamic tenferro surface crates.

Examples

use tenferro_internal_error::{Error, Result};

fn maybe_fail(flag: bool) -> Result<()> {
    if flag {
        Ok(())
    } else {
        Err(Error::InvalidTensorOperands {
            message: "demo".into(),
        })
    }
}

assert!(maybe_fail(true).is_ok());
assert!(maybe_fail(false).is_err());

Variants

RuntimeNotConfigured

The runtime used by builder .run() was not configured.

Backend(Error)

Wrapper for backend/linalg/einsum errors from tenferro crates.

Autodiff(AutodiffError)

Wrapper for AD-rule level errors from chainrules-core.

InvalidTensorOperands

Tensor operands are structurally invalid for the requested operation.

Fields

message: String

MixedReverseGraph

Reverse-mode operands belong to different value graphs.

Fields

expected: u64

found: u64

UnsupportedRuntimeOp

Operation is not available for the currently selected runtime.

Fields

op: &'static str

runtime: &'static str

UnsupportedAdOp

AD operation is not available for the requested mode.

Fields

op: &'static str

UnsupportedStructuredLinalg

Linalg operation is available only for dense tensor inputs.

Fields

op: &'static str

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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 From<AutodiffError> for Error

fn from(source: AutodiffError) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.
