Enum ShapeConstraintEvalError 

pub enum ShapeConstraintEvalError {
    MissingInput {
        input_idx: usize,
        input_count: usize,
    },
    AxisOutOfBounds {
        input_idx: usize,
        axis: usize,
        rank: usize,
    },
    Overflow,
    Underflow,
    DivisionByZero,
}

Typed reason that a symbolic shape constraint could not be evaluated.

Examples

use tenferro_runtime::ShapeConstraintEvalError;

let cause = ShapeConstraintEvalError::MissingInput {
    input_idx: 2,
    input_count: 1,
};
assert_eq!(
    cause.to_string(),
    "shape expression references input 2, but only 1 inputs were provided"
);

Variants

MissingInput

An expression referenced an input shape that was not supplied.

Fields

input_idx: usize

Referenced input index.

input_count: usize

Number of supplied input shapes.

AxisOutOfBounds

An expression referenced an axis outside the selected input’s rank.

Fields

input_idx: usize

Referenced input index.

axis: usize

Referenced axis.

rank: usize

Rank of the selected input.

Overflow

Checked dimension arithmetic overflowed usize.

Underflow

Checked dimension subtraction underflowed usize.

DivisionByZero

A floor-division divisor evaluated to zero.

Trait Implementations

impl Clone for ShapeConstraintEvalError

fn clone(&self) -> ShapeConstraintEvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeConstraintEvalError

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

Formats the value using the given formatter.

impl Display for ShapeConstraintEvalError

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

Formats the value using the given formatter.

impl Error for ShapeConstraintEvalError

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<DimExprEvalError> for ShapeConstraintEvalError

fn from(error: DimExprEvalError) -> Self

Converts to this type from the input type.

impl PartialEq for ShapeConstraintEvalError

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