Enum EvalError

    Missing {
        op: usize,
        tensor: String,
    },
    OutOfRange {
        op: usize,

    DivideByZero {

    },
}

Why a graph has no value, by name.

Variants

Missing

A tensor an op reads that nothing gives a value: no input, no fill, no op before it.

Fields

op: usize

tensor: String

OutOfRange

A row, position or index outside what the program declares — the check the program’s statements make.

Fields

op: usize

what: String

Overflow

An integer past i64, where the VM would widen to an arbitrary-precision Int the graph’s tensors do not hold.

Fields

op: usize

what: String

Operand

An operand whose element type or length is not the one the op reads.

Fields

op: usize

tensor: String

why: String

DivideByZero

An integer division by zero.

Fields

op: usize

Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Error for EvalError

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 EvalError

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